Student's Guide

In addition, DOE has issued guidance on use of

air monitoring results when there is a technology

shortfall in Radiological Control Technical Position

(RCTP) 2001-01, Questions and Answers

Concerning Acceptable Approaches to

Implementing Bioassay Program Requirements.

In part, RCTP 2001-01 states that, when there is

a technology shortfall for bioassay and air

monitoring results indicate exposures greater than

100 millirem in a year are likely, one should

assess dose based on the air monitoring results.

As a minimum, personnel who perform operations

in controlled areas should wear coveralls and

shoe covers. For inspections or visits, lab coats

and shoe covers may be permissible. When

contaminated wet areas are to be entered, water-

repellent (plastic or rubber) clothing shall be worn.

No personal outer clothing should be permitted

under coveralls.

Hands should be protected by a minimum of two

barriers; for example, at least one pair of

surgeon's gloves and one pair of rubber gloves

should be worn.

Protective clothing should be removed at the step-

off pad, and personnel monitoring for

contamination shall be performed.

Respiratory protection equipment shall be readily

available. Respiratory protection equipment

should be used for all bag-out operations, bag

and glove changes, and any situation involving a

potential or actual breach of confinement.

Protection, in the form of air-purifying or

atmosphere-supplying respirators, shall be used

whenever concentrations of radionuclides in the

air are likely to exceed the applicable DACs.
