The effects of three photoperiods (24 hr illumination, 12 hr illumination +12 hr darkness and 24 hr darkness) and three salinities (20‰, 30‰ and 35‰) on the uptake of 60Co and 137Cs for Chlorella sp.and on the growth of its algae are studied.The uptake of 60Co for the algae is two orders of magnitude higher than that of 137Cs.Of factorial effects, the effect of photoperiod is most significant either on the uptake of the radionuclides or on the growth of the algae; the effect of salinity comes next in order and that of their interaction remains with the last.The uptake of the two radionuclides increases with extended photoperiod while the uptake of 137Cs declines with increasing of salinity.The growth of the algae appears to be the best under the conditions of 24 hr illumination and 30‰ salinity.
