Recommended for targeted testing for contaminants commonly responsible for radioactivity in drinking water. Certified lab testing Fast turnaround at lab (24 business days) Standard shipping included Expert treatment advice This is the most comprehensive package Tap Score offers specifically designed to address an array of radiological concerns. This testing package analyzes for an array of contaminants related to radioactivity: gross alpha particles, gross beta particles, uranium, potassium, potassium-40, radon, radium-226, radium-228, cesium-137, and strontium-90. This testing is ideal as followup testing for client's with known radiological issues in their drinking water and can help pinpoint the exact source. If you are unsure about the radiological content of your drinking water, this cost-effective, broad radiological scan is recommended as a starting point: Full Radiation Water Test. While radioactivity in water is often due to naturally occurring factors, such as uranium in nearby bedrock, elevated radioactivity levels in water may also be attributed to close proximity to: waste facilities, heavy agricultural activity, or oil and gas activity. It is estimated that ~170 million Americans drink tap water contaminated by radiation. Long term exposure to low levels of radiation in drinking water is a serious health hazard, especially for pregnant women. This Tap Score water test package provides all required materials to properly collect and submit a sample for certified laboratory testing. Reported results will include detailed, quantified analysis of all parameters tested. Note: If no total strontium is detected, then results are completed within 12 working days. If total strontium does include a detection, then subsequent analysis will continue in order to obtain a result for strontium-90. This second phase of analysis may require up to 3 weeks to obtain an accurate result.
