TITIE A Eleetronoseopic study of the lungs with chronic radiation sickness induced by radioactive strontium MIODICAL: Radiobiologiya, v. 1, no. 4p 1961,, 56,"68 TEM In previous research the authors found that the administration of radioactive strontium in doses sufficient to cause acute radiation sickness induced changes in the lung tissue (hyperemiap hemorrhage, etc.) after I - 2 days (Ref. 1: Piziol. zh.j 69 1960), and with chronic radia,.. tion sickness after 2 - 3 days (Ref. 2: Tez. dokl. nauchnoy konferentaii p:i problemes 1%echebnoye i diagnosticheskoye primeneniye radioaktivnykh izotoopov (The Therapeutic and Diagnostic Use of Radioactive Isotopes) Khartkovq 1960 ). Howeverv there were indications that submicroscopic l*sions ensued much earlier. The present work was an attempt to check this. Tests were run on white rats.

The animals were killed off at periods ranging from I bour to 108 days after irradiationg and slides were prepared from their organs .t,xamined under an ",-3M- 100 (UEM-100) electron microscope) at magnifica- tions of 1500 - 30tOOO. Only one hour after the adminiatration of radioactive strontium, marked edema of the epithelial and endothelial cells and the connective tissue of the alveolar septa were noted. Par- ticularly large Tacuoles were distributed through the protoplasmatic plates of the andothelial and epithelial cells. The lesions affected all the strata of the alveolar septa, blood vessels, bronchi and the pleura. Dense dark granules appeared in the epithelial cells. The authors consider the changes in the membranes and connective tissue layers of the alveolar walls particularly noteworthy sin--.e they were of a marked dynamic nature) connected with the courae of radiation sickness. Irk the early period of radiation sickness (I - 7 days), the membranes become thickened, edematous, pultaceous and delaminated, while at later periods (40thq 90th and 108th days) they are densely packed. An radia- tion sickness develops, the layers of connective tissue thicken and Card 2/3 3036,9 S/20ti/61/001/00,1/019/032 Electronoscopic study of... &N/D303 develop incorrectly orientated coarse fiberse Electronoscopic examina- tion, therefore, reveals early changes in the cells and membranes of the lung tissue which, to a certain extent, explain the appearance of early hemorrhages in the lungs. The thickening and hardening of the membranes and connective tissue layers at later stages explains the deterioration in the gas metabolism in cases of chronic radiation sickness.

In its mc,st effect.1ve &lge 60 mglkg of body weight, propyl gallate increased the surv:.val rate o."' the irradiated animals and extended the average life span of the 'Irradia.. ted mice to 19.6 days ( 8~8 days in the contro' series ), The injection of propyl. gallate a"LBo postponed the perind of the height of clinical sym- P-.,,.%ma of acute radiation sickness from 6 -- 10th day to 9 - 1"ith day after ir.radJatJo-n.

PURPOSEs The book is intended for radiobiologists and other specialists in medicine who are working on radiation protection problems. COVERAGEt The monograph summarizes the original research carried out by the authors and includes data on the therapeutic properties,, pharmacclogy, and toxicology of ganates. It has been established that injection of gallates into the test animals prior to their exposure to LD of radiation insures 50% survival. The most important properties of ganates consist in their ability to significantly reduce radiation effects in the organism even after their application during 2 - 4 hours following irradiation. There are 348 references, mostly non-Soviet. q~~L4~ AFnC/a4D/ASD/X44DC/APGC L 1660 FI) S123 -0/63/009/0WOM/C03 AUMOM boy2 V. A4 Tirm.

A study was made of the biological effecto (thermal, elec- trical, photo-chemical, and mechanical) produced by a ruby laser emitting an energy of one joule with a 5-uoec pulse. The biological effect can be studied by measuring the energy of the laser emission absorbed by the irradiated object. The absorbed energy can be measured by using calorlmetricq chemical, and photographic methods. Photometry makes possible simple and c.onvenient evaluations of the absorption and reflection of laser radiation by biological objects. The photographic method can be used to study the absorption by different objects (blood, blood plasma, skin, muscular tissues, different organs and tissues of the animal organism# biological media) and to study the effect of 1 L 32940-66 X NRs AT6022262 pigment coloration on the magnitude of the absorbed radiation energy. The effect of scattered and focused laser radiation on different biological objects, particularly the effect of focused beams on speci- mens of human and animal bloods was investigated. The elastic (ultra- sonic) oscillations appearing under the effect of laser radiation in solid bodies, liquids, and various biological media were also inves- tigated. The duration of the ultrasonic pulses, which were observed by3neans of-a piezoelectric detector, was somewhat longer than the duration of laser pulses. The fundamental component of the ultrasonic pulse corresponds to the frequency rAnge of 40 to 50 Kc. The ultra- sonic pulse lags in comparison with the laser pulse by the time required for the propagation of elastic oscillations in the irradiated object.

In addition the construction of new power plants with in- creased and super-hi h steam pressures is required. Steam superimposing ~parovaya nadstroyka'i and gas tur- bine extension (gazoturbinnaya pristroyka) may be used for expanding existing thermal power plants.- Under 11steam superimposing" the authors understand an addi- tional cycle connected to the basic operation cycle of a thermal power plant. The waste heat of this ad- Card 1/6 ditional. cycle is used for obtaining superheated, or, The Problem of Expanding Existing Power Plants SOV/143-58-11-10/16 dry, saturated steam. It is assumed that the super- heating of steam for the installation to be superim- posed is achieved by the heat of the fuel. The "gas turbine extension" means the connection of an addition- a-1 cycle during which a considerable amount of the heat, used for obtaining dry, saturated steam, and the heat, required for superheating, are provided by the fuel. Figures I to 3 are graphic representations of these additional cycles. These diagrams show that any steam superimposing leads to an efficiency increase which is also confirmed by three equations which are used for determining7?. The power limitation of gas turbine will create some difficulties when combining the latter with steam turbines. The authors then in- vestigate in somewhat more detail various possible power plant reconstruction systems taking into con- sideration locally available fuel. In case only solid fuels are available, steam superimposing or gas tur- bine extension with a closed cycle may be used. The Card 2/6 authors consider the reconstruction of two turbine SOV/143-58-11-10/16 The Problem of Expanding Existing Power Plants types: VK-100-2 (90 0atmospheres, 480 0C) and AK-50 (29 atmospheres, 400 C). By comparison and thermo- dynamic analysis the authors arrive at the conclusion that an initial steam pressure increase above 300-350 atmospheres will not provide a noticeable fuel saving. In this connection, the upper steam superimposing parameters are indicated with 300 atmospheres and 6500 0, corresponding to the initial parameters of the SKK-300 turbine. Considerable results are achieved when superimposing the 29 atmosphere unit, since here, intermediate superhegting and a feed water temperature increases to 280-300 C may be used. The gas turbine extension is justified only in case the cost per in- stalled kilowatt is lower than that of steam superim- posing, i.e. when the excess in fuel consumption is justified by lower amortization costs. The authors then consider power plants at which gas and coal are available as fuels. In this case, beside the steani superimposing an open-cycle gas turbine may be used, Card 3/6 using the arrangement shown in figure 7. Such a gas SOV/143-58-11-10/16 The Problem of Expanding Existing Power Plants turbine cycle was suggested by Professor Ya..I. Shnee and Engineer A.A. Lisatkin ZR__ef 17. Yfith this system, it is possible using solid fuel in the steam boiler. The efficiency of such a combine unit with a VK-100-2 turbine is 36.7% at a superimposing power of 58,000 kilowatts. For reducing the heater surface and in- creasing the possible unit power of the gas turbine, a semi-closed cycle may be suggested, as shoiNm in figure 8. The power of such unit will amount to 40,700 kilowatts, having a somewhat lower efficiency (35.6%) than the aforementioned unit. However, the regenerator and water-gas heater surfaces are reduced by 30-40%. The gas turbine plant consists of one main turbine and auxiliary gas turbines, driving axial compressors and electric generators. Finally, the authors consider power plants using only liquid or gaseous fuels. In this case the open cycle gas tur- bine unit may be used which will be more economical when using a VK-100-2 turbine than the steam super- Card 4/6 imposing with steam parameters of 300 atmospheres and The Problem of Expanding Existing Power Plants 65000. The efficienc of such a system, working on natura; gas (8533 CM with an initial gas temperature of 700 C, is 38.3% with the VK-100-2 turbine an-d _~4.8% with the AK-50 turbine. The authors comriared the vario-as possible superimposing and extension systems, This comparison is shown in table 1. The authors a~r_ rive at the following conclusions: 1) From the thermo- dynamic viewpoint, only such a gas turbine extension will be more effective at which the internal regenera- tion of the gas cycle is highly develop,~A., 2)' in a number of cases, a gas turbine extension be more profitable than steam superimposing of existing powe-r- plants, provided liquid or gaseous fuel is available, This pecularity is especially obvious when superim- posing power plants wi8h initial steam paramet-ers of 90 atmospheres and 480 C. 3) The lower the parameters of the steam section of the existing po~-.rer plant, the relatively higher the superimposing of such power plants will be. The efficiency of superi-IT)Osed power Card 5/6 plants having lower steam parameters will exceed in SOV/143-58-11-10/16 The Problem of Expanding Existing Power Plants some cases also by absolute values the efficiency of superimposed plants with higher steaj,i paranieters. 4) Using semi-closed gas turbine cycles for superim- posing facilitates a considerable reduction of the heater surfaces and dimensions of units with a sma2l reduction of the profitableness.

TITILi: Some Slectrical Properties of Thin Layers of Tellurium and Germanium (Rekotoryye elektricheskiye svoystva tonkilch sloyev tellura i germaniya) PERIODICAL: Izvestiya Vysshikh Uchebnykh Zavedeniy, Fizika, 1958, Nr 4, pp, 91-96 (USSR) ABSTRACT: The dependence of resistivity on temperature, voltage- current characteristics and limiting current densities ,was determined for thin layers of tellurium and germanium condensed in vacuo onto bases of various materials at various temperatures. Some relations between resistivity and deformation were also established. The main conclusions, derived from measurements described below,were: 1) The resistivity of germanium films is fairly stable with time. The change in resistivity with deformatlign is about 2.3% for a relative-deformation of 4.5 x 10 2) The resistivity of tellurium films is not stable. Mechanically such films are not durable. The change in resistivity with deformation is about half that of Card 1/8 germanium films. Some Electrical Properties of Thin Layers of Telluri-Lua and Germanium Pre-paration of S~ecimens. The thin films were pE~duced 4 by condensation in a vacuum of bhe order of lxlO to 5xic mm Hg in the form of strips 4 mm across and 30 mm loni;. The ends of the strips were overlapped for I to 2 am by 5 x 9 mm. rectangles of metal, also vacuum-condensed, to which copper wires were soldered, The metal contacts for tellurium were always of nickel, but tin was also tried for germanium. The bases used were mainly glass, but in special cases polymerized VL-7 lacquer on a metal disc, juica and fused quartz were tried. The bases were heated by radiation from a current-carrying tantaliun wire placed above the base and the temperature was controlled by a copper-constantan thermocouple attached to the surface of the base. The tell1irium from which the specimens were made had less than 10-'4% impurities. The germanium used had a specific resistivity of 4 to 20 Ohm.cm. In all cases the conductivities were of the hole type. B~Cperimental Results and Discussion. a) Tellurium condensed onto a cold base. Fio'.1 shows Card 2/8 the log of the resistivity (which was of the order of some SOV/139- 1-58-4-151240 Some Electrical Properties of Thin Layers of Tellurium and Germanium hundred thousand Ohms) plotted against recip-1,ocal of the absolute -temperature. The resistivity in air at a given temperature clearly increases after thermal cyclinG, as it also does for specimens stored at room. temperature. 'This increase is irrevezsible. 0 b) Tellurium condensed onto a hot base (150-160 C). Fig.2 shows again a rapid resistivity increase after an initial thermal cjcle. There is no further chan~.,re after some 4 to 5 thermal cycles. Fig-3 shows the difference in characteristics for chanGes in the atmospheric environment. Experiments started at the moment of preparation of -the specimen and carried out in vacuo are shown by the curves be6inning at the asterisk and marked by white cycles on the Graph. These characteristics arg approximately two straiE;ht line segments with a break at 9OuC.- After each cycle a lower resistance was obtaineda However, after leaving the specimen in vacuo at 130 0 for 30 mins, the resistivity increased - without reachinG its initial value. When air was admitted Card 3/8 in-to the system resistance fell and the curves with the SO V/ 139 - 58-4-15/30 Some Electrical Properties of Thin Layers of Tellurium and Germanium black dots were obtained. The final curve was strai..--hter and had a sfflaller gradient. When the same specimen was examined after 10 days in air, the curves at the bottom of Fi .5 were obtained. These are approximately strai,"J_rlt lines Subsequent evacuation of the system did notu- reproduce the original properties of the specimen, though its resistance increased. c) Germanium. Specimens condensed onto a cold base showed resistivities of the order of 10 megohas, while those condensed onto bases heated to 500-550 C showed resistivities between 7 and 30 kOhms (most lay between 10 and 16). It can be verified that in the hot-base specimens the layer structure is crystalloE;raphic, (see Refs 1 and 2). Specimens condensed in the same experiment onto bases of glass, mica and fus.-d quartz showed practically identical resistivities, of the order of 12 kOhms. The resistivities of all specimens showed little change after ageing in air: 1,% increase after 40 days. The resistivity temperature relationship wap Card 4/8 close to exponential between room temperature and 130 OC. E "il 13 9- 563 -4- 15/30 Some Electrical Properties of Thin Layers of Tellurium and Germanium The points obtained by repeated thermal cycling lay fairly accurately on a single characteristic curve. It is noted in (Ref 3) that there is a significant change in resistivity for extension or compression of specimens of PbS.Fu:fthermore, there are theoretical (RelPs 4,5) and experimen~tal (Ref 6) grounds for a deformation'- resistivity relationship for germanium monocrystals. The deformation in the experiments, on thin layers of Te and Ge, here described, was produced by the method described in (Ref 3) and measured optically -to an accuracy of 1-~L. For tellurium each deformation cycle produced an irreversible increase in resistance. A single cycle is shown in Fig.4. For germanium the resul s were independent of -the cyling history, and are shown in FiG.5.

The static voltage-current characteristics of' tellurium and germanium were strictly linear for current densities UP to 300 A/cM2 and 400 A/cm 2 respectively. The dynamic characteristics, taken on an oscilloscope, were strictly linear; increasing voltage and the corresponding heating changed the gradient of the characteristic. Discussion. Takemaro Sakurai et al. (Ref 7) have already noted the irreversible changes in resistivity u of thin tellurium layers condensed onto cold bases. They explained the effect by stating that such layers have a micro-crystalline structure with amorphous patches between crystals and that heating causes the crystals to grow at the expense of the amorphous patches. The effect does not occur in layers condensed onto hot bases at temperatures below that at which the specimen. was condensed, which is in accordance with the above Card 6/8 explanation. Such specimens behave in the same way as SOV/139-58-4-ljc/30 Some Electrical Properties of Thin Layers of Tellurium and Germanium those out -from the solid. The authors point out that this theory is too simple to explain all the effects noted in the experiments doccribed; for exwiple, the coincideece of characteristics for specimens measured below 90 0 in vacuo with those cut from the solid. The effects can be explained by introducing two Uhe properties of additional considerations: first, - surface levels, described by E. Clark (Reg 8), which explain the break in characteristicsat 90 C when all surface levels are occupied and, secondly, the additional acceptor levels produced by oxygen at the layer surface. Subsidiary considerations are the effect of water vapour which may affect the surface ionic conductivity and the diffusion of oxygen into the depths of the specimens creating conduction electron traps. For tellurium the noise level makes measurement Card 7/8 difficult.

(Ref 1). The sensitivity of such gauges is higher by an order of magnitude than the sensitivity of wire gauges, although they cannot compete with the latter because of lack of stability and reproducibility of their parameters. The present authors consider the problem as to whether it is in principle possible to manufacture germanium film strain gauges with rpproducible characteristics. It is argued that the change in the resistance of a germanium film on deformation is determined ',.:)y two factors, namely, deformation of the grains leadIng to a change in the band stru~-txire of the semiconductor and a change in the resistance of the material between grains,or the presence of microcracks Cardl/3 62344 S/139/60/000/03/01/045 E034E;14 Dependence of the Stress Sensitivity on e uency for Thin Films of Germanium and 11porosity". If the change in the resistance of the gauge is not due to an alteration in the band structure but to the other causes, then it wi.Lil be difficult to manufacture probes with reproducible characteristics. If, on the other hand, the strain effect is assDCiated with the band structure, then reproducible r;haracteristics can be obtained. The two effects can be separated by measuring the resistance of poly-erystalline specimens at high frequencies (Refs 3,4,5). The present authorv have carried out these measurements and have obtained the resistance of germanium films as a function of frequency. The resistance was measured to an accuracy of about 75'0. The results obtained are shown in Figure 1, which plots the resistance and the change in the resistance as a function of frequency. As can be seen, the resistance decreases,. beginning at 40 Mels and continues to decrease down to about 60 Mc/s, the total decrease being.about 15%~ the change in the resistanceon the other hand. in this Card2/3 region remains constant. These results indicate that the ~K 6 2,q 44 S/139/6o/oo0/03/041/045 EOJI/E314 Dependence of the Stress Sensitivity on requency for Thin Films of Germanium contribution due to the band-structure effect is the predominating one.
