THE PRODUCTION OF CHROMOSOME ABERRATION IN CHIRONOMUS RIPARIUS (DIPTERA: CHIRONOMIDAE) BY TRITIATED WATER
Keyword(s):
AbstractChironomus riparius was used to determine whether an increased frequency of chromosome aberrations could be detected in the progeny of an aquatic organism reared in tritiated water (HTO). An increased frequency was detected in larvae whose progenitors had developed either in 250 or 500 μCi/ml of HTO (2500 to 5000 times MPC for occupational exposure). The radiosensitivity of C. riparius to acute gamma radiation was determined and compared with the results obtained with tritiated water. The frequency of aberrations produced by incorporated tritium was approximately the same as the frequency produced by an equivalent dose of chronic gamma irradiation.
