EPA 935 Polonium 210 Determination Test in Water
The EPA 935 method is a critical analytical procedure used to determine the presence and concentration of polonium-210 (Po-210) in water samples. Polonium-210, an alpha-emitting radionuclide, poses significant health risks when ingested through contaminated water sources. This test is essential for ensuring that drinking water meets regulatory standards set forth by the United States Environmental Protection Agency.
The EPA 935 method involves several steps to ensure accurate and reliable results:
- Sample Collection and Preservation: Water samples are collected from various sources, including municipal supplies or specific points of interest. Samples must be stored under appropriate conditions to prevent contamination or degradation.
- Precipitation: The sample is then subjected to a precipitation process using silver nitrate (AgNO₃) and silver diethyldithiocarbamate (Ag-DDC). This step helps in separating the Po-210 from other components of the water matrix.
- Solvent Extraction: After precipitation, the sample undergoes a solvent extraction process to enrich the polonium content. This involves using organic solvents that selectively extract Po-210 for further analysis.
- Radioactivity Measurement: The enriched sample is then measured using high-purity germanium (HPGe) detectors or other suitable gamma-ray spectrometers. Calibration standards are used to ensure accurate quantification of the radioactivity.
The EPA 935 method is robust and widely accepted for its precision and accuracy. However, it requires specialized equipment and trained personnel due to the handling of radioactive materials involved.
Compliance with EPA guidelines ensures that water supplies are safe from harmful levels of Po-210, which can accumulate in the body over time, leading to increased cancer risks. By adhering to this stringent testing protocol, laboratories like Eurolab contribute significantly to public health and environmental safety.
