of internal contamination by way of ingestion, absorption, inhalation
or wound contamination. Decontamination procedures should NOT increase
penetration of radioactivity into the body by excessive abrasion of the
the contaminated area with an appropriate survey meter. Remove contaminated
clothing and place in bag.
- If the
skin is not broken, rinse the contaminated area with tepid water.
- If the
contamination persists use a mild, non-abrasive soap by rubbing the
lather gently about the contaminated area for about three minutes and
then rinse thoroughly with tepid water. Repeat if necessary. Try household
vinegar to remove P-32.
- If the
contamination persists, notify the Radiation Safety Coordinator.
- If the
skin is broken in the contaminated area, wet-swab the area taking care
not to spread the activity into the wound. It may be necessary to clip
contaminated nails or hair, if decontamination attempts fail.
