Summary
Cesium 137 levels were measured in Belarusian children visiting Italy. Radiocesium levels varied, and body distribution was uniform, allowing biological half-life calculation.
Area of Science:
- Environmental Science
- Nuclear Physics
- Public Health
Background:
- The Gomel district in Belarus remains a risk area for radioactive contamination.
- Cesium 137 is a significant radionuclide of concern due to its long half-life and potential health impacts.
Purpose of the Study:
- To measure Cesium 137 levels in children from Belarus temporarily residing in Italy.
- To analyze radiocesium distribution within the body and calculate biological half-life.
Main Methods:
- Whole body counter measurements were performed on 70 children.
- Radiocesium levels in urine samples were analyzed for 50 children.
- Collaboration with radiation protection services in Ispra and Trino Vercellese was established.
Main Results:
- Radiocesium levels in children ranged from approximately 10 Bq to several thousand Bq.
- Uniform distribution of radiocesium was observed in children with high levels.
- Comparison of body and urine Cesium levels enabled biological half-life determination.
Conclusions:
- The study provides data on internal Cesium 137 contamination in children from a high-risk area.
- Understanding radiocesium distribution and biological half-life is crucial for assessing health risks.
- This research highlights the importance of monitoring radionuclide levels in vulnerable populations.
