Radon levels in Omani drinking and irrigation water are safe for consumption. Measurements show concentrations well below international safety limits, ensuring water quality in the region.
Area of Science:
- Environmental Science
- Radiological Health
- Water Quality Assessment
Background:
- Radon in drinking water poses potential health risks.
- Assessing radon levels is crucial for regional water quality management.
Purpose of the Study:
- To measure radon concentrations in drinking and irrigation water in Eastern Oman.
- To evaluate the radiological safety of water sources in the Jalan BBH region.
Main Methods:
- Utilized passive track etch detectors (LR-115 type II) for time-integrated radon measurement.
- Employed high-resolution optical microscopy for precise radon concentration analysis.
- Collected water samples from diverse sources across Eastern Oman.
Main Results:
- Radon concentrations ranged from 140 Bq m-3 (irrigation well water) to 363 Bq m-3 (drinking water).
- All measured values were significantly below the US-EPA's permissible limit of 11.1 kBq m-3.
- Calculated annual effective doses (0.38-0.99 μSv y-1) were below the WHO's recommended action level of 0.1 mSv y-1.
Conclusions:
- Omani water sources in the studied region are radiologically safe for consumption and use.
- The collected data provides a baseline for future radiological studies in the region.
- No immediate health concerns are indicated from radon in the assessed water supplies.
