Fwd: [CSHEMA-L] Lead bricks powdering

[Thomas J Shelley <tjs1@CORNELL.EDU>]

Dear Colleagues--The following is forwarded from the mailing list of 

the Campus Safety, Health, and Environmental Management Association, 

an organization of the National Safety Council.  Could you please 

respond to our colleague's question on lead bricks and dust?  I would 

think that a standard operating procedure incorporating lead dust 

management would be in order.  Exposure monitoring and perhaps 

medical surveillance may be in order, also.  Any advice from our 

expert subscribers?  Please respond to Kim as well as to the list. 

Thanks.  Tom

Hey all:



I received a question from our Physics department and am seeking input from

those more knowledgeable than I on the subject.



Their lead shielding bricks produce a "powder" when handled.  They are

wearing gloves to minimize contact when having to move the bricks, but are

wondering if there are other methods that might be more successful at

reducing the dust - painting the bricks seems to be an option used at some

locations - but appears to be more applicable to applications where the

bricks are more permanently located  (here they are not, we move ours

frequently).



I'm sure some of the radiation experts out there have encountered this

before.  Please share the knowledge...



Thanks.

Kim
