Recommended as a broad screen for radioactivity in drinking water from any source. This package is frequently recommended for people served by a private well. Certified lab testing Fast turnaround at lab (12 business days) Standard shipping included Expert treatment advice This Tap Score water test package provides all required materials to properly collect and submit a sample for certified laboratory testing. Reported results include analysis of Alpha Radiation and Beta Radiation from any source–including radium, uranium, cesium, and strontium, etc. While each of these individual sources can be tested and quantified individually, this broad radiological screen is recommended unless you already suspect a specific problem. Alpha and beta radiation can be emitted by naturally-occurring radioisotopes of radon, uranium, radium, and other radioactive sources as well as by man-made radionuclides such as radioisotopes of strontium, and cesium. Long term exposure to low levels of radiation in drinking water is associated with increased cancer risk. Note that this test does not individually identify the sources of radiation. If you have specific concerns about radon gas in particular, it is recommended that you test for radon specifically. This Full Radiation Water Testing package is included in the Extended City Water Test and Extended Well Water Test.
