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.
