Interaction of Low Doses of Ionizing Radiation, Potassium Dichromate and Cadmium Chloride in Artemia franciscana Biotest
The influence of cadmium chloride (at concentrations of 100 and 200 mg l-1) and potassium dichromate (at a concentration of 50 mg l-1) along with the effect of gamma radiation 60Co (at a dose of 10 and 50 Gy) on lethality to Artemia franciscana was investigated. Four different interactions were studied, namely, those of potassium dichromate and gamma radiation, cadmium chloride and gamma radiation, and combinations of potassium dichromate and cadmium chloride in interaction with gamma radiation. A significant (α = 0.05) decrease was observed in lethality due to exposure to radiation (10 Gy) in comparison with action of only potassium dichromate and cadmium chloride or their combination without exposure to gamma rays. These results support the theory of hormesis.
