THE RESPONSE OF SOME HEALTH PHYSICS INSTRUMENTS TO SODIUM-24 AND CHLORINE- 38 ACTIVITIES IN POLYTHENE MANPHANTOMS AND THE HUMAN BODY
Technical Report
·
OSTI ID:4086282
Measurements were made of the response of five commonly used health physics instruments when held near polythene man-phantoms filled with aqueous solutions containing sodium-24 and chlorine-38. The ratios of the wholebody chlorine-38 and sodium-24 activities are calculated for various periods of accidental human irradiation by neutrons. These ratios and the phantom results are used to estimate the response of the five instruments when held near the human body at various times after irradiation. Relative contributions of the chlorine-38 and sodium-24 to the instrument indications are listed. The tabulated data enable the instrument readings to be converted to wholebody sodium- 24 activity at the time of irradiation. This may be used as a quick estimate of the degree of neutron irradiation. (auth)
