Detection of Radiation in Drinking Water


Radiological materials in drinking water are a serious problem, both from the perspective of an attack on the country or typical, everyday environmental regulations.

We plan to integrate our gamma detector capabilities with Clarion's existing Sentinal water protection system to provide detection of radionuclides.

Given below are the United States EPA requirements for radiological materials in drinking water to give a general idea for the scale of detection required by such a system, followed by a diagram demonstrating a typical water treatment and distribution system in which the radiation detection system would be implemented.


EPA Requirements for Concentration of Radiological Materials in Drinking Water

Regulated Radionuclide Maximum Contaminant Level (MCL)
Beta particles/proton emitters 4 mrem/year
Gross alpha particle activity 15 pCi/L
Combined radium-226/228 5 pCi/L
Uranium 30 mg/L
