  • Part 17: Transportation of radioactive materials.
  • Part 22: Physical protection of category 1 and category 2 quantities of radioactive material.

The proposed rule changes to these radioactive materials related regulations are needed to conform to recent minor federal rule changes of the U.S. Nuclear Regulatory Commission and to make minor editorial corrections. The purpose and intent of each proposed change is described in the side margin comments of the draft rules below.

Note that the proposed rule changes will not impact facilities that use only x-ray machines.
