Part 3 Radioactive substances parametersI1
England and Wales
TABLE D:
Prescribed values for radon, tritium and indicative dose of water intended for human consumption
Parameters | Maximum concentration or value | Units of Measurement |
|---|---|---|
(1) Enforcement action by the local authority is deemed justified on radiological protection grounds without further consideration where radon concentrations exceed 1,000 Bq/1. | ||
(2) If tritium concentration exceeds its parametric value, an investigation (which may include analysis) of the presence of artificial radionuclides must be carried out. | ||
| Indicative dose (for radioactivity) | 0.10 | mSv |
| Radonf1 | 100 | Bq/l |
| Tritium (for radioactivity)f2 | 100 | Bq/l |
