Gross Beta Particle Activity
Occurrence/Use
Gross beta particle activity is a measure of the total amount of radioactivity in a water sample attributable to the radioactive decay of beta-emitting elements. Beta particles usually travel greater distances in air than alpha particles (about 6 feet) before being absorbed.

| California PHG Comments: |
The documents provide some perspective on the carcinogenic potency of the radionuclides included in the categories of gross alpha and gross beta, at the screening levels of 15 pCi/L for gross alpha and 50 pCi/L for gross beta/photon emission. We have not suggested Public Health Goals (PHGs) corresponding to these screening levels, since the screening levels are by definition analytical tools, not final regulatory limits. |
