What is Gross Beta?
Gross beta activity is a screening measurement for beta-emitting radioactive particles in water, including potassium-40, strontium-90, and tritium. It indicates the total beta radiation level rather than a single radionuclide. The EPA maximum contaminant level is 4 millirem per year. Elevated gross beta readings are associated with increased cancer risk, particularly leukemia and bone cancer from long-term exposure.
Who is most at risk in Dayville?
Gross Beta matters most for infants, pregnancy — a radioactive contaminant with no safe level — developing tissues in infants and during pregnancy are more sensitive to radiation. The safe level for these groups is stricter than for a healthy adult.
How to remove Gross Beta from your water
Install a point-of-use reverse osmosis system certified to NSF/ANSI Standard 58, which removes the majority of dissolved radionuclides that contribute to gross beta activity.
Use an ion exchange system, either cation or anion exchange depending on the specific radionuclide identified, to target the primary contributors to the elevated reading.
Request a detailed radiological analysis from a certified laboratory to identify which specific beta-emitting radionuclides are present before selecting a treatment approach.
Replace filter membranes and dispose of spent media according to your state's radioactive material guidelines, and retest water annually to confirm continued performance.
