Monitoring Gamma Radiation

The Neighborhood Environmental Watch Network, known as NEWNET, is able to give early indications of increases in radiation due to radioactive particulates in the air.

About the Calculator

Information for this calculator was taken from the "Personal Radiation Dose Chart," pamphlet published by the American Nuclear Society (ANS), © 1990. Data came from this reference and from the DOE Office of Environmental Management site. In the case of discrepancies between two dose estimates, a reasonable approximation between the values was made.
