Abstract：ObjectiveTo analyze the chromosome aberration rates in peripheral blood lymphocytes on oil well logging workers. MethodsOne hundred fifty six oil well logging workers (radiation group) and 60 healthy people (control group) were chosen to observe and compare their per capita annual dose equivalent and chromosome aberrations. Results(1)Cell aberration rate in the radiation group (0.60%) were higher than that of the control group (0.22%)(P<0.05), with the higher chromosome-type aberration rate (0.28%), chromoatid-type aberration rate (0.65%), acentric fragments(0.56%) (P<0.05) in the radiation group.(2) “Dicentric+ring” aberration rate (0.10%) of the 5 to 10-year seniorities was higher than that of those working for more than 15 years (P <0.05) in the radiation group.(3) Aberrations rate were highest in those the neutron dose equivalent per capita were above 0.20mSv, with cell aberrations rate (1.16%), chromoatid-type aberration rate (0.55%), acentric fragments (1.03%)(P<0.01),chromosome-type aberration rate (0.61%),“dicentric+ring” aberration rate (0.13%) (P<0.05). ConclusionsOil well logging workers have higher rates of chromosomal aberrations in peripheral blood lymphocytes, especially in the workers with the higher neutron dose equivalent per capita.
