Effect of detergents on radiothermoluminescence of Chlorella

Radiothermoluminescence (RTL) of Chlorella cells cultivated in a medium in the presence of a detergent was studied as a function of their contact time with the detergent in the temperature range from -196 degrees to +150 degrees C. The concentration of the toxicants blocking cell division caused noticeable changes in the shape of the liminescence curve beginning 1.5 h after adding the detergent to the medium. Additional luminescence peaks were noted in the -95 degrees and +120 degrees temperature region. A correlation was found between the change of luminescence intensity at -95 degrees bleaching of the cells, and their viability as a function of their contact time with the detergent.
