RESULTS OF GAMMA IRRADIATION OF RADIOTECHNICAL PARTS
The fact that the mechanical and electrical properties of materials and parts used in radio engineering can be modified by gamma irradiation was utilized to study the behavior of radio sets in radiation fields and to develop radioresistant sets. A series of resistors were irradiated with gamma rays, one low-ohmic and one high-ohmic resistor of the same type in each experiment. The parameters were measured before and after gamma irradiation in a pit at a dose rate of 1 x 0.1 x 60 g, 650 rep/sec before and after gamma irradiation. The initial integral dose amounting to 100 x 10/sup 6/ rep was increased to 1100 x 10/ sup 6/ rep in intervals of 100 x 10/sup 6/ rep. Measurements showed that the conductivity of all the low-ohmic resistors remained constant even at the maximum integral dose. The conductivity of high-ohmic resistors with a very thin conductive layer was, however, changed. As the radiation dose is increased, the resistance of the various types increases by 25 and 3%. (OTS)
