【Abstract】 Objective To estimate the dose of medical diagnostic X-ray workers. Methods The chromosome aberrations were analyzed by G-banding or FISH in medical diagnostic X-ray workers with different calendar years of entry. Results The biological doses estimated by the two methods were in agreement with the doses evaluated by physical methods. Conclusion G-banding and FISH are effective ways to analyse the chromosome translocations.更多还原
