Abstract:
In this study, we have concentrated measuring range of alpha particle in air, tissue and bone using energy for element that emit alpha particle from uranium series. And investigate the correlation between the range of alpha particles and cancer in lung and bone and using equations to describe the effect of alpha particle in human tissue. United nation data suggested that 3*10’Bq could induced lung cancer. The National Radiological Protection suggested that the average exposure to ionizing radiation in United Kingdom is now 2.5 mSv/year at 1988, compared with just under 2.2 mSv/year at 1984 in United State. In this study, we have concentrated measuring range of alpha particle in air, tissue and bone using energy for element that emit alpha particle from uranium series.
