Calculated Radioactivity
See Help on Radioactivity for background on the calculation.
| Estimated Radioactive Strength (ERS) |
Remarks |
 |
barely detectable - Radioactivity detected only by very sensitive instruments. |
 |
mild - Very low level of Radioactivity, no special precautions needed. |
 |
weak - Low level of Radioactivity, may show on average radiation equipment. |
 |
strong - Noticeable Radioactivity, limit exposure and handling. |
 |
very strong - Very Radioactive, limit exposure, handling and use secure storage. |
 |
dangerous - Potentially lethal. Store only small amounts in lead container. |
| * | Thorium estimated from Rare Earth Element content. |
