Abstract

Rapid and simple age determination procedures important for civil defense were developed. The model substances for the explosion products used in experimental work were **2**3**8U, **2**3**5Pu fission products. The sensor was a Si(Li) semiconductor detector. The procedure based on the quotient of overall pulses measured above two different discrimination levels yielded satisfactory accuracy of age determination in the interval of 20 to 600 hours. The procedure based on continuous observations of dose rate decrease is serviceable in the interval of at least 2 to 1000 hours, but presumable longer on. The two portable instruments built at Gamma Works, Budapest allow measurements to be made on site.
