The following is a summary of information … The following is a summary of information provided by the Louisiana Department of Environmental Quality (the Department) via phone:</br>The licensee reported that a package received from the Colorado School of Mines, containing a 1.166 mCi Co-57 source (model MC07.122, serial number: 31.23, manufacturer unknown at the time of the report) had measured external dose rates of 50 mr/hr on contact and 0.2 mr/hr at 1 meter. When the external packaging was opened, it was discovered that the internal shipping container had been damaged. It is believed that the damage to the internal shipping container degraded the effectiveness of the shielding, resulting in the external radiation levels measured. The Department will follow-up with additional information as it is developed.</br>* * * UPDATE ON 09/15/2025 AT 1319 EDT FROM JAMES PATE TO ROBERT THOMPSON * * *</br>The following is a summary of information provided by the licensee via email:</br>The package was supposed to be an excepted package.
