- As you probably already know dingo, there are several different measures.
-
- 1) The amount needed for prompt morbidity. In which case Pu is well down
- the list behind several common poisons and toxins.
-
- 2) The amount needed for cumulative exposure to cause systemic collapse.
- In which case Pu is behind Berylium and Lead as well as several organic
- toxins.
-
- 3) Prompt radiologic poisoning. Pu, being an alpha emitter, is again down
- the list behind beta and gamma emitters. You can hold it in your hand
- without fear of harm. In quanities of a few grams, it's warm to the
- touch.
-
- 4) Cumulative radiologic poisoning. If trapped in the lung, Pu is
- about on a par with Polonium, the suspected culprit in tobacco
- smoke. If ingested, it doesn't stay in the body and the harm is
- statistically in the noise compared to it's chemical toxicity.
-
- Compared to a number of industrial chemicals routinely shipped in
- bulk, Pu is much less hazardous. Provided it doesn't get dispersed
- in an aerosol, it's danger in an accident is minimal. Mad bombers
- not withstanding, there's little reason to be concerned about
- shipments of Pu in secure containers.
