DOE-STD-1098-99
Radiological Control
Conduct of Radiological Work
June 2004
315 Technical Work Documents
1.
Technical work documents, such as procedures, work packages, or job or research plans, should be used to control
hands-on work with radioactive materials. Requirements for incidental or routine work activities that involve a low
potential of worker exposure or workplace contamination, such as the collection of trash or used protective
clothing, should be established in generally applicable procedures.
2.
Technical work documents used to control radiological work activities should be reviewed and approved by the
radiological control organization.
3.
Radiological control hold points should be incorporated into technical work documents for steps that require action
by the radiological control organization to assess existing radiological conditions or prevent significant adverse
radiological consequences during subsequent steps.  Sites should define "significant adverse radiological
conditions" that require the use of radiological control hold points in the site-specific radiological control manual.
The following activities and potential conditions should be considered for inclusion in the requirements for
radiological control hold points:
a.
Radiological control organization action needed to assess changing radiological conditions and ensure
implementation of required controls
b.
Potential for radiation doses in excess of the applicable site-specific administrative control level
c.
Potential for elevated airborne radioactivity levels (e.g., levels exceeding 10 times the DAC values provided
in Appendices A and C of 10 CFR 835)
d.
Potential for elevated removable surface contamination levels on accessible surfaces (e.g., levels exceeding
100 times the Table 2-2 values)
e.
Potential for unplanned or uncontrolled release of radioactive material to the environment.
4.
The radiological control hold point should include the criteria that must be met or action that must be taken to
satisfy the hold point prior to continuing with subsequent steps in the planned activity.
316 Control of Internal Exposure
1.
The primary methods used to maintain individual internal doses ALARA shall be physical design features, such as
confinement, ventilation, and remote handling [see 835.1001(a)]. The design objective shall be, under normal
conditions, to avoid releases of radioactive material to the workplace atmosphere. The objective, under all
conditions, shall be to control inhalation of radioactive material to levels that are ALARA [see 835.1002(c)].
2.
Administrative controls, including access restrictions and the use of specific work practices designed to control
airborne radioactivity, shall be used as the secondary method to maintain internal doses ALARA [see 835.1001(b)].
