In late April 2023 the department began a stakeholder process for Part 4 of the Colorado Rules and Regulations Pertaining to Radiation Control titled “Standards for protection against radiation”. The stakeholder comment period ended on May 29, 2023 and we received no comments. At the request for rulemaking before the Colorado Board of Health on July 19, 2023, the Board scheduled a rulemaking hearing for September 20, 2023. Due to a filing error, the hearing for Part 4 is rescheduled for October 18, 2023. See the notice of rulemaking hearing below for additional information.
This rule change will revise section 4.18.3 to replace the current language with a recordkeeping requirement related to determining the need for occupational monitoring. The recordkeeping requirement is specific to certain persons required to register under Part 2. In addition, we are proposing minor editorial and formatting corrections and changes for consistency with other current radiation regulations.
To understand the changes being proposed, interested parties are encouraged to review all of the documents on this page, including:
- The Part 4 draft proposed rule (April 2023).
- Part 4 detailed summary.
- The Part 4 complete rulemaking schedule.
In April 2023 the department began a stakeholder process for Part 3 of the Colorado Rules and Regulations Pertaining to Radiation Control titled “Licensing of radioactive material. The stakeholder comment period ended on May 15, 2023 and no comments were received. At the request for rulemaking before the Colorado Board of Health on July 19, 2023, the Board scheduled a rulemaking hearing on September 20, 2023. Due to a filing error, the hearing for Part 3 is rescheduled for October 18, 2023. See the notice of rulemaking hearing below for additional information.
The proposed changes to this regulation updates an existing provision, and introduces a new general license section relating to antiquity items containing radium-226. Radium-226 was incorporated into some consumer and other products in the early 1900’s and later. These antiquity items may include watches, clocks, gauges used in military vehicles, revigator jars or urns, small radium calibration sources, all of which may contain radium-226.
The addition of this language to the rule is expected to be an overall benefit to stakeholders and others who have or intend to possess antiquity items containing radium-226. The proposed change will provide a general license path that does not currently exist in Colorado regulation. The changes being proposed have been in federal rule and the regulations of many other states for a number of years.

Following an extensive stakeholder process, on November 18, 2020, the Colorado Board of Health adopted the Part 20 TENORM rule along with related changes to the Part 12 regulation. The new rule became effective on January 14, 2021 and is enforceable beginning July 14, 2022.
