Radiological Safety Training for Plutonium Facilities
DOEHDBK11452001
Instructor's Guide
To avoid long-term depletion, Ca-DTPA is
administered initially, then followed with Zn-
DTPA. Ca-DTPA should never be used in the
treatment of pregnant women since it could
cause birth defects.
Substantial dose reductions can be achieved if
DTPA is administered within a few hours
(recommended within one hour) of the intake.
Dose reductions from 10% to 90% have been

in the lesson.
If a large amount of contamination is located at
the wound site, excision can dramatically
reduce the exposure. Dose reductions of up to
a factor of 100 have been achieved with
excision.

Usually, only a small amount of tissue is
removed. This does not present a significant
health hazard.
