How to use this tool
Each radionuclide presents a different relative hazard due to its half‐life and decay scheme. This table provides the basis for categorizing radionuclides according to relative hazard. It is the foundation for the QLM quantities in Table 3.1 in the Radiation Safety Manual.
For the quantities below:
* H‐3 in the form of labeled DNA bases is limited to 100 uCi/day.
** 100 uCi of I‐125 and I‐131 can be disposed of to the sewer with prior approval of Health Physics.
