Conduct of Radiological Work
Training in accordance with Table 3-1
Worker's signature on the RWP
Respiratory protection when specified by the RWP or other written authorization
Pre-job briefing for high contamination or airborne radioactivity areas, as applicable
Personnel dosimetry, as appropriate.
Individuals exiting contamination, high contamination, or airborne radioactivity areas should remove protective
clothing (See Appendix 3C for recommended procedure). When entering an uncontaminated area, these individuals
shall be monitored, as appropriate, for the presence of contamination on their skin and clothing [see 835.1102(d)].
These individuals should perform whole body frisking to detect personnel contamination in accordance with Article
Exit points from contamination, high contamination, or airborne radioactivity areas should include the following:
Step-off pad located outside the exit point, contiguous with the area boundary
Step-off pads maintained free of radioactive contamination
Designated containers inside the area boundary for the collection of protective clothing and equipment
Contamination monitoring equipment located as close to the step-off pad as background radiation levels
Multiple step-off pads should be used at the exits from high contamination areas. Use of multiple step-off pads is
described in Appendix 3C.
Protective clothing and monitoring provisions specific to benchtop work, laboratory fume hoods, sample stations,
and gloveboxes are identified in Article 347.
Article 421 provides requirements and guidance for removing materials and equipment from these areas.
336 Member of the Public Entry Provisions
Site procedures should identify area entry requirements and access restrictions for members of the public.
Members of the public with a demonstrated need to enter the following areas may be allowed access if such access
is controlled with a combination of orientation and the use of escorts trained for the specific area:
Radiological buffer areas
Radioactive material areas
Soil contamination areas
Underground radioactive material areas
Members of the public should be prohibited from entering very high radiation, high radiation, high contamination,
and airborne radioactivity areas.
Orientation provisions for members of the public are identified in Article 622.
337 Controlling the Spread of Contamination
Controls shall be implemented as necessary to prevent the spread of removable contamination outside of radiological
areas under normal operating conditions [see 835.1102(a)]. The extent of these controls is dependent upon the type and
level of contamination present and the activities in and around the area. The following measures should be used to
