Code 310.110, if the licensee knows or has reason to believe that a sealed source has been ruptured. The written confirmation shall designate the well or other location, describe the magnitude and extent of the escape of licensed material, assess the consequences of the rupture, and explain efforts planned or being taken to mitigate these consequences.
b) The licensee shall notify the Agency of the theft or loss of radioactive material, radiation overexposures, excessive levels and concentrations of radiation, and certain other accidents as required by 32 Ill. Adm. Code 340.1205, 340.1210, 34.1220, and 340.1230.
c) If a sealed source becomes lodged in a well, and when it becomes apparent that efforts to recover the sealed source will not be successful, the licensee shall:
1. 1) Notify the Agency by telephone at (217) 782-7860 of the circumstances that resulted in the inability to retrieve the source and:
