RE: Alternatives to lead blankets

[Darren_Boone@RL.GOV]

Let's not pick apart the wording here, the request for information is valid.

Whereas the lead contained in the blanket may not be respirable, etc. the

wrapping material presents a problem for many of us from a fire loading

perspective.

Betreff:	Alternatives to lead blankets



I have been asked to gather data on non-hazardous alternatives to lead

blankets for gamma shielding.  Any input will be appreciated.

Dave,

 I have some problems with your request. Your posting would imply, that lead

blankets are hazardous. ?????? Very basic radiation protection knowledge

would show you, that the shielding efficiency depends on the Z of the

shielding material. Better than lead would of course be uranium, depleted

uranium available at very low cost. According to the last few years news on

gulf war syndrome etc. this seems to be a "very dangerous and hazardous

material". (Sometimes I am cynical...) Maybe you want to use bismuth?



Yes, lead blankets are hazardous if they fall on the feet from great

heights.



Could you please inform us on your profession and what is the reason to ask

such a question on RADSAFE?



Franz
