| Abstract:: |
| Objective To explore the relationship between high background radiation and injurious effect on inhabitants. Method Peripheral blood samples were collected from the inhabitants of 10, 40, 55 and 70 years old in high background radiation areas (HBRA) of Yangjiang, Chromosome preparations were carried out with conventional whole blood microculure. Results The percentage of dicentric chromosome with fragments in inhabitants of HBRA was significantly higher than that in control areas (CA) (4.69‰ vs. 3.15‰, P<0.01), and there was an increase in the aberration frequencies with age (or accumulated doses). Conclusion Chromosome aberration is an extremely sensitive indicator of radiation damage and a good radio biodosimeter. |
