New Gamma-Ray Exposure Estimation Method for Radiation Accident

There occurred in 1971 an accidental exposure to γ-rays from an ¹⁹²Ir source received by persons not regularly occupied in radiation work. To serve in planning the therapeutical treatment, a method for estimating the γ-ray exposure received by these persons was devised.

The method is based on the idea of using bearing jewels collected from the patients' wrist watches as monitor sample for tests on their thermoluminescence. Applying this method, it was estimated that the exposure sustained by the three patients in question was 761, 77 and 40 R. The method thus developed should prove useful for estimating the exposure sustained by patients involved in a radiation accident.
