ISO 28135 Strontium-90 Quantification in Leafy Vegetables
The ISO 28135 standard provides a robust methodology for quantifying the presence of Strontium-90 (Sr-90), an artificial radionuclide, within leafy vegetables. This service is crucial for ensuring that food products meet international safety standards and regulatory requirements related to radioactivity in foodstuffs.
Leafy vegetables are a key component of many diets worldwide. They often absorb contaminants from soil during growth. Strontium-90, a byproduct of nuclear fission reactions, can be present in the environment due to historical or current nuclear activities. The presence of Sr-90 in leafy vegetables can pose risks if it exceeds permissible levels.
The ISO 28135 standard outlines specific procedures for extracting and quantifying Strontium-90 from leafy vegetable samples using advanced instrumental techniques such as liquid scintillation counting (LSC) or gamma spectroscopy. These methods ensure accurate detection of radioactive isotopes at extremely low levels, which is essential for maintaining public health.
The process begins with the collection and preparation of fresh leafy vegetables. Specimens must be thoroughly washed to remove any surface contaminants. The cleaned samples are then processed into a homogenous solution suitable for analysis. The extracted Sr-90 undergoes further purification steps before being measured using sensitive detection equipment that adheres strictly to the ISO 28135 protocol.
Results from this testing procedure provide critical data on the radioactivity levels within leafy vegetables, enabling food producers and regulators to make informed decisions about product safety. Compliance with such tests ensures adherence to international standards like IEC 60599 and EN 14182-7, which govern radiation limits in food.
By adhering strictly to the ISO 28135 methodology, laboratories can ensure reliable quantification of Strontium-90. This not only supports regulatory compliance but also enhances consumer confidence by verifying that food products meet stringent safety benchmarks.
| Sample Preparation | Detection Method | Data Analysis |
|---|---|---|
| Washing, homogenization, and extraction of Sr-90. | Liquid scintillation counting or gamma spectroscopy. | Analyzing results against ISO 28135 thresholds for permissible levels. |
The precision and accuracy provided by this testing method are paramount in ensuring that food products meet international safety standards. By leveraging these techniques, laboratories can play a pivotal role in safeguarding public health and upholding global food quality benchmarks.
