A rapid method for the determination of dose equivalent in mixed radiation fields

Dose equivalent in mixed radiation fields of a extended energy range is generally determined by using a combination of several detectors. The need for a rapid evaluation of a radiation situation can be fulfilled by a rem-meter based on a combination of a tissue-equivalent ionization chamber and an organic scintillator, the latter showing a light-output depending on linear energy transfer (LET). Comparisons between results from such an instrument and those from multidetector techniques were performed in stray radiation fields around a GeV proton accelerator and are reported here. (14 refs).
