Suitability of sterin dose indicators for control of certain food irradiation processes

Sterin indicator, a new label dosimeter was evaluated for reliability and s uitability as a device for discriminating and monitoring radiation treatmen t. Two versions, Sterin-125 and Sterin-300 were irradiated with gamma rays at dose ranges of 75-175 Gy and 200-400 Gy respectively. The irradiated sam ples were evaluated subjectively using Multiple Comparison Difference techn ique and their stability was tested under dark and differing light and temp erature conditions. The results showed that these Sterin labels are general ly reliable and useful but are affected by doses lower than designated thre shold and by extended exposure to light sources.
