PART 1 Radioactive Material Identification, Storage, and Control

411 General

Materials in contamination, high contamination, or airborne radioactivity areas shall be considered contaminated

until surveyed and released [see 835.1101(a)]. Any equipment or system component removed from a process that

may have had contact with radioactive material should be considered contaminated until disassembled to the extent

required to perform an adequate survey, surveyed, and shown to be free of contamination at levels exceeding the

Table 2-2 values. These survey and release provisions do not apply to airborne radioactivity areas where only

gaseous, short-lived (half-life of 1 hour or less) radionuclides are present. Detailed provisions for release of

materials from radiological areas are provided in Article 421.

Radioactive material located within radiological areas does not require specific labeling or packaging if sufficient

information is provided to allow individuals to take appropriate protective actions [see 835.606(a)]. The

information may be provided by means of postings, pre-job briefings, training, or other appropriate means.

The radiological control organization should develop response and notification requirements associated with a loss

of radioactive material, including searches, internal investigations, documentation, and reporting. The radiological

control organization should be notified in the event of a loss of radioactive material.

412 Radioactive Material Labeling

10 CFR 835 requires labeling of individual containers of radioactive material and radioactive items except under

certain specified conditions in which existing postings and control measures provide adequate warning [see

835.605(a) and 835.606(a)].

Postings and access control requirements for radiological areas generally provide sufficient personnel protection to

negate the need for individual container or item labeling; however, items having removable contamination in excess

of the Table 2-2 values should be labeled when used, handled, or stored in areas other than contamination, high

contamination, or airborne radioactivity areas.

Required labels shall include the standard radiological warning trefoil and the words "Caution" or "Danger" and

"Radioactive Material" [see 835.605]. The "Danger" heading should be used when an individual exposed to, using,

or handling the material could receive a dose equivalent exceeding any applicable administrative control level in

one hour. The radiation warning trefoil shall be black or magenta and imposed upon a yellow background [see

835.601(a)]. Magenta is the preferred color for the trefoil and the lettering.
