Subject: Weighting Factor for Hot Particle Skin Doses per Cm^2
Jan. 23, 2003
Dear Radsafers:
This question is probably for health physicists at nuclear power plants.
If you have a worker who received a face skin dose from a single "hot
particle", expressed as rad/cm^2, what weighting factor do you use in
adding it to his other doses? While the original Part 20 specifies a
weighting factor of 1.0 for a head dose, the Statements of Consideration
for Part 20 state that "The use of other weighting factors for external
exposure may be approved on a case-by-case basis upon request to the NRC."
(Fed. Reg. 56(98):23369; May 21, 1991.)
I assume that a case must have been made to NRC for "hot
particles". Anyone know what the weighting factor is?
Much obliged for your help in advance.
Ciao, Carol
