It has long been recognized that exposure to low levels of toxic chemicals could have beneficial effects, such as increased resistance to related chemicals or stimulation of growth or development. The notion of radiation hormesis, that exposure to lo

The effects of ionizing radiation were examined in terminally differentiated cells using nucleated chicken erythrocytes (RBCs) as the model. We used a hemolytic assay to score radiation damage to RBCs. Chicken RBCs received 0 to 100 Gy of radiation a

This study reports the first demonstration within a single insect genus (Tribolium) of both the acute, or lethal-midlethal, dose-independent pattern of mortality, and the hyperacute, dose-dependent pattern, after appropriate doses of ionizing radiati

Shortly after γ-irradiation, flour beetles (Oklahoma strain of Tribolium confusum ) exhibited and decline in resistance to oxygen toxicity. Beginning about two weeks after irradiation, however, the LD 50 exposure time in pure oxygen was much greater

The combined effect of single or fractionated /sup 137/Cs gamma radiation and 2 h of 2450-MHz microwave radiation at two different power levels, resulting in specific absorption rates of 680 or 760 W/kg in distilled H/sub 2/O, was investigated in the

Populations of flour beetles (Tribolium castaneum and T. confusum) were sexually segregated as pupae, and subpopulations were later X-irradiated. The irradiation produced increased longevity in both sexes of each species. The magnitude of the effect
