Abstract
The human health risk due to the prolonged exposure to the low-level radioactive and non-radioactive materials in an environment is now to be evaluated based on the quite the same procedures especially in the cell and molecular (DNA) level. This suggests that the risk evaluation studies for the radioactive and non-radioactive pollutants might be crossed over for mutual benefit in the preventive risk-based management of environmental micro-pollutants based on the common framework.
