Management of Used 99Mo/99mTc Generators

Section 1: Objective

1. The objective of this regulation is to set out specific safety requirements for the management of used $^{99}\mathrm{Mo}/^{99\mathrm{m}}\mathrm{Tc}$ generators.

Section 2: Scope

2. This specific regulation applies to facilities that:

a. Use and manage $^{99}\mathrm{Mo}/^{99\mathrm{m}}\mathrm{Tc}$ generators for medical purposes;

b. Manage used $^{99}\mathrm{Mo}/^{99\mathrm{m}}\mathrm{Tc}$ generators for non-medical purposes that are not cleared from regulatory control.

3. This specific regulation does not

Section 4: General Requirements

4. For the management of used $^{99}\mathrm{Mo}/^{99\mathrm{m}}\mathrm{Tc}$ generators in Type A facilities, the authorized person shall select one of the following options:

a. Store the generators in the facility for decay of radioactivity until their clearance from regulatory control;

b. Transfer the generators to an authorized Type B facility prior to their clearance from regulatory control; or

c. Return the generators to the Supplier prior to their

11. For monitoring gamma radiation dose rates and performing beta contamination checks of used $^{99}\mathrm{Mo}/^{99\mathrm{m}}\mathrm{Tc}$ generators, the authorized person shall ensure that:

a. Suitable and appropriately calibrated survey meter and contamination monitor are available;

b. Beta contamination checks are performed using the most sensitive scale of the contamination monitor;

c. Monitoring of gamma radiation dose rates and beta contamination checks are performed for the whole generator, and separately for the generator's column and shielding;

d. Records with the results of
