Assessment of the potentially beneficial uses of krypton-85. Final report, Task 64

Projection of needs for gamma radiation sources and other radioisotopes and assessment of alternatives for providing radiation sources

“…Nondestructive testing applications of 85Kr are primarily for flaw detection in metals and electronic components, gauging, leak detection, sensing and position indicating (Eggers and Gaurthrop 1975;NTIAC 1978). Some of these are reasonably well developed, e.g., flaw detection, leak detection and gauging, while others are not as well developed.…”

“…The heat produced by 85Kr decay is 0.623 Wt (watts thermal} per gram, and the specific activity is 392 curies per gram (Chart of the Nuclides 1977;Rohrmann 1968;and Rohrmann 1971). Thus 85Kr is a useful heat source, its beta energy can be used to produce light, and the gamma activity can be used in nondestructive testing applications (International Study of Terrestrial Applications of Radioisotopic Power Sources 1966Sources -1967Eggers and Gaurthrop 1975;and Rohrmann 1974).…”
