OAR 333-113-0403: Radiation Surveys and Records: Radioactive Contamination Control

(1) If the licensee detects evidence that a sealed source has ruptured or licensed materials have caused contamination, the licensee must initiate immediately the emergency procedures required by 333-113-0205. (2) If contamination results from the use of licensed material in well logging, the licensee must decontaminate all work areas, equipment, and unrestricted areas. (3) During efforts to recover a sealed source lodged in the well, the licensee must continuously monitor, with an appropriate radiation detection instrument or a logging tool with a radiation detector, the circulating fluids from the well, if any, to check for contamination resulting from damage to the sealed source.
