Radiological Control
Conduct of Radiological Work

3.
Minimum requirements for unescorted entry into high radiation areas shall include radiation safety training [see
835.901(b)], a primary dosimeter [see 835.402(a)(5)], a radiation survey, and supplemental dosimeter [see 835.502(a)]
and should include the following:
a.
Training in accordance with Table 3-1
b.
Worker's signature on the RWP.
4.
Minimum requirements for unescorted entry into high radiation areas where dose rates exist such that an individual
could exceed a whole body dose of 1 rem in one hour shall include radiation safety training [see 835.901(b)], a
primary dosimeter [see 835.402(a)(5)], a radiation survey, and supplemental dosimeter [see 835.502(a)] and should
include the following:
a.
Training in accordance with Table 3-1
b.
Worker's signature on the RWP
c.
A determination of the individual's current dose, based on primary and supplemental dosimeter readings
d.
Pre-job briefing, as applicable
e.
Review and determination by the radiological control organization regarding the required level of radiological
control technician coverage.
5.
Individuals shall be prevented from unauthorized or inadvertent entry to very high radiation areas [see 835.502(c)].
In addition to the controls required in Articles 334.2 and 334.3, a survey should be performed prior to the first entry
to the area after the source has been secured or shielded to verify the termination of the very high radiation field.
6.
Operations personnel should immediately notify the radiological control organization of operational or system
changes that could result in significant changes in radiological hazards. Such notifications facilitate ra diological
control organization actions to erect postings and implement required entry controls.
7.
The number, issue, and use of keys should be strictly controlled where locked entryways are used to control access
to high and very high radiation areas.
8.
The radiological control organization should maintain a list of high and very high radiation areas.
9.
Written procedures should be implemented to ensure the effectiveness and operability of barricades, devices,
alarms, and locks. Determination of the effectiveness of these control devices should also consider individual
training and response. Weekly inspections of the physical access controls to high and very high radiation areas
should be performed to verify controls are adequate to prevent unauthorized entry.
335 Contamination, High Contamination, and Airborne Radioactivity Areas
1.
Minimum requirements for unescorted entry into contamination areas shall include radiation safety training [see
835.901(b)] and protective clothing [see 835.1102(e)] and should include the following:
a.
Training in accordance with Table 3-1
b.
Worker's signature on the RWP, as applicable
c.
Personnel dosimetry, as appropriate.
2.
Minimum requirements for unescorted entry into high contamination or airborne radioactivity areas shall include
radiation safety training [see 835.901(b)] and protective clothing [see 835.1102(e)] and should include the following:
