There is no set number of areas required to be surveyed, but you must ensure that all radioactive material use areas within the lab are covered.
Survey records must be maintained for three years after the date of the survey.
There are no specific requirements for where survey records must be maintained. Survey records must be readily available for inspection by Research Laboratory & Safety Services or outside regulatory agencies.
The area must be immediately decontaminated and a documented follow-up survey must be performed to show that contamination does not exceed the action level.
The action level for contamination is 50 counts per minute (cpm) above the background count rate.
All surveys (both monthly and after-use) must include:
The method depends on what radionuclide(s) your approval is approved to possess and use:
Any radiation worker listed on your approval may perform and document a monthly survey.
Every room listed on your RAM approval must be surveyed. Monthly surveys may be limited to RAM storage areas during calendar months in which RAM is only in storage and not in use.
Monthly surveys must be performed every calendar month in which radioactive material is possessed.
Yes, all approvals in possession of radioactive material (including in storage and in waste) any time during a calendar month must perform a monthly survey unless the approval has been granted a specific approval condition exempting them from the requirement.
The after-use survey is performed to ensure your radioactive material (RAM) workspace is free of radioactive contamination after each use radioactive material. The monthly survey is performed to ensure all the rooms on your approval are free of radioactive contamination.
Monthly surveys are required to ensure your approved radioactive material use/storage areas are free of radioactive contamination.
