Re: Nuclear medicine rooms shielding

Hassan, it really depends on the hot lab.  If you are only using unit doses
from a central pharmacy then very little lead, if any is required.  Many
departments get by with using a few lead bricks at their dose drawing
stations.  A lead lined waste container is sometimes needed if you do not
return your unit dose syringes.  Now if you do not use unit doses and you
get a 15 curie generator then the shielding requirements change.  If this
is the case store the generators in two inch thick lead boxes.  This amount
of shielding will work well for the ~780 keV photon from Moly.  If you have
additional questions drop me a line.

3-4 mm of lead will be enough? Are there a way to calculate the required
shielding exactly, what are the reference ?
