(a)

The materials are constantly attended during these periods by an individual who takes the precautions necessary to prevent the exposure of individuals to radiation or radioactive materials in excess of the limits established in this division; and

(b)

The area or room is subject to the licensee’s control.

(2)

Rooms or other areas in hospitals that are occupied by patients are not required to be posted with caution signs pursuant to OAR 333-120-0410 (Precautionary Procedures: Posting Requirements) provided that:

(a)

A patient being treated with a permanent implant or therapeutic radiopharmaceutical could be released from confinement pursuant to OAR 333-116-0260 (Release of Patients Containing Therapeutic Quantities of Byproduct material or Permanent Implants) and 333-116-0265 of this chapter; and

(b)

There are personnel in attendance who will take the necessary precautions to prevent the exposure of individuals to radiation or radioactive material in excess of the limits established in this division and to operate within the ALARA provisions of the licensee’s radiation protection program.

(3)

A caution sign is not required to be posted in a room or area containing a sealed source, provided the radiation level at 30 centimeters from the surface of the source container or housing does not exceed 0.05 mSv (0.005 rem) per hour.
