RE: Pu Toxicity vs DDT

["Lieskovsky, Miro" <MLieskovsky@nbpower.com>]

Radsafers:

Being no expert in Pu, just for the curiosity, here is the compiled
data using the iaea ss-115, table ii-vi.  (an infant of less than 1
year):

Pu Isotope	T1/2		eg			decay constant	Activity		Dose
		years		Sv/Bq			s-1			Bq.g-1		Sv
238		87.7		4.00E-06		2.5E-10		6.3E+11		3E+06
239		2.40E+04	4.20E-06		9.2E-13		2.3E+09		1E+04
240		6.50E+03	4.20E-06		3.4E-12		8.5E+09		4E+04
241		14.4		5.60E-08		1.5E-09		3.8E+12		2E+05
242		3.80E+05	4.00E-06		5.8E-14		1.4E+08		6E+02

The committed effective doses per ingestion of 1g of Pu isotopes 238-242
range from 600 to 3 000 000 Sv for an infant.  Others are similar. 

I do not know what kind of assumptions one should use for the committed
doses because of the acute effects or whatever else, but I for one do
not want to swallow any of that stuff. 

yep, this is not "just for a chat" issue by all means.
