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.
Section 351.695 Particle Accelerators
No licensee or registrant shall permit above-ground testing of particle accelerators, designed for use in well logging, which results in the production of radiation, except in areas or facilities controlled or shielded so that the requirements of 32 Ill.

d) The shipping papers for the transportation of radioactive material required by 32 Ill. Adm. Code 341;
e) When operating in the State under reciprocity as provided for in 32 Ill. Adm. Code 330.900, a copy of the appropriate license, certificate of registration, or equivalent documents authorizing the use of licensed material;
f) The dates and results of the most recent tests for leakage or contamination performed on the sealed sources; and
g) A copy of the licensee's radioactive material license, including all appropriate amendments.
Section 351.770 Notification of Incidents and Lost Sources; Abandonment Procedures for Irretrievable Sources
a) The licensee shall immediately notify the Agency by telephone and, subsequently within 30 days, by confirmation in writing, using an appropriate method listed in 32 Ill. Adm. 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.
