Abstract |
Description of a case where a radiation worker was referred to hospital with radiation injury to both hands after working for 3yrs with iridium-192 sources; 2yrs later the chromosome aberration technique was used to assess accumulated radiation dose, as he had continued in radiation work. From a blood sample lymphocyte cultures were made and 500 metaphase spreads were examined, with the following results: dicentrics, 49; centric rings, 7; acentric rings, 10; interstitial deletions, 31; terminal deletions, 21. It is claimed that studies of this kind illustrate the valuable contribution of chromosome analysis to radiological protection practice, espcially where there is a lack of reliable physical dosimetry data, as well as to the eventual evaluation of risk of the late effects of radiation in terms of acute biological effect. |
