Radioactive Contamination Control
Section 351.690 Radioactive Contamination Control
a) If the licensee detects evidence that a sealed source has
ruptured or licensed material has caused contamination, the licensee shall
immediately initiate the emergency procedures required by Section 351.630.
b) If contamination results from the use of licensed material in
well logging, the licensee shall decontaminate all work areas, equipment, and
unrestricted areas.
c) During efforts to recover a sealed source lodged in the well,
the licensee shall 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.
