Phase 5: Full scope of research with some scale limitations
Monthly surveys are not required when there is no radioactive material in your inventory (including in storage and in waste) for the entire calendar month.
The approval has been given a special condition from the Radiation Safety Committee(s).
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.

All surveys (both monthly and after-use) must include:
The method depends on what radionuclide(s) your approval is approved to possess and use:
