The effect of temperature on cesium-137 metabolism in the oriental cockroach, Blatta crientolis, was studied. Adult and nymphal animals were fed cesium-137 to investigate the biological half-time, excretion rate, retention curve and distribution of the isotope among the body tissues.Metabolic rate studies at different temperatures showed an exponential relationship between oxygen consumption and temperature. The Q10 was 2.56 for adults and 2.20 for nymyhs in the 10℃-35℃ range.Cesium-137 elimination rate increased as environmental temperature increased. The Q10 for cesium-137 elimination was constant (1.2) over the 15℃-35℃ range and greatly increased over the 10℃-15℃ range (2.05 and 16.4). The gut had a high concentration of cesium-137. Concentration in the cuticle, as well as in other tissues or organs examined were very similar.
