(CONTAMINATION CRITERIA)

1. If the equipment will be used in a radiation permitted room/area, the level of removable contamination should be under 3 Bq/cm² for most of the radionuclides used in U of T (meet the criteria from Appendix C from the CNSC Document Licence Application C-222).
2. If the equipment will be removed from a radiation permitted area/room for reuse or disposal, the level of removable contamination should be under 0.5 Bq/cm² for all beta and gamma emitters and under 0.05 Bq/cm² for all alpha emitters averaged over an area of 100 cm².
3. If the fixed contamination cannot be reduced to a level less than 0.5 microSv/h measured at a distance of less than 0.5 m from the equipment, the equipment cannot be reused in an unauthorized radiation area or disposed of as regular waste.
4. If it will be reused in an authorized radiation area the equipment should be marked with radiation sign. If the dose rate is above 2.5 microSv/h, the level of radiation field should be marked on the equipment
5. If the equipment is intended for disposal and the levels of fixed or removable contamination cannot be reduced to below the criteria (from points 2 and 3) on the equipment/parts of the equipment, the equipment or parts of the equipment will be disposed of as radioactive waste.
6. If the equipment/parts of the equipment intended for disposal can be decontaminated to meet the criteria (from points 2 and 3), the equipment/parts of the equipment will be disposed of as regular waste. Before doing so, be sure that the equipment/parts of the equipment meets the applicable criteria for biological or chemical hazardous material, if applicable.
