10 CFR Part 19: Notices, Instructions & Reports to Workers

What Is 10 CFR Part 19?

10 CFR Part 19 is a federal regulation issued by the U.S. Nuclear Regulatory Commission (NRC). Its full title is Notices, Instructions, and Reports to Workers: Inspection and Investigations. It establishes the legal rights of radiation workers and the corresponding duties of licensees — the companies or organizations that hold an NRC license to operate a nuclear facility. Every nuclear power plant operating under an NRC license must comply with Part 19. Understanding this regulation is not optional; working at a licensed facility without following it exposes both the worker and the employer to legal liability.

Who Does Part 19 Cover?

Part 19 applies to two main groups:

• Licensees — employers who hold an NRC license (such as a nuclear power plant utility).
• Workers — any individual who is employed by the licensee or by a contractor and who may receive occupational radiation doses or who handles licensed radioactive materials.

The regulation uses the phrase individuals working under a licensee broadly. If you work on a nuclear plant site in a role that involves potential radiation exposure, Part 19 protections apply to you.

Key Requirements for Licensees

Instructions to Workers. Licensees must instruct workers in the health protection problems associated with exposure to radiation and radioactive material, the precautions and procedures to minimize exposure, and the purposes and functions of protective devices. Workers must receive this instruction before they begin work in a radiation area and must be told what to do if they encounter an emergency.

Posting of NRC Form 3. Licensees are required to post NRC Form 3, Notice to Employees, in a conspicuous location where workers can see it. NRC Form 3 summarizes workers' rights under NRC regulations — including the right to request exposure records and the right to report safety concerns to the NRC. The posted copy must be current; the NRC updates Form 3 periodically, and licensees must replace outdated versions promptly.

Posting of Notices of Violations. If the NRC issues a notice of violation or a proposed imposition of civil penalties against the licensee, and the NRC specifies that it must be posted, the licensee must post that notice where affected workers will see it. This transparency requirement is central to nuclear safety culture.

Notifications of Incidents. Licensees must notify workers of incidents involving radiation or radioactive material that could affect the workers' health and safety. Affected workers must receive this notification as soon as practicable.

Rights Granted to Workers

Right to Exposure Records. Workers have the right to request, and the licensee must provide, a copy of the worker's radiation exposure records. A worker may request their accumulated dose history. The licensee must respond to this request and cannot refuse or retaliate.

Right to Request Inspections. Workers — or representatives of workers — may request an NRC inspection if they believe a violation of NRC regulations has occurred or that an unsafe condition exists at the facility. The NRC must keep the identity of the requesting worker confidential if requested.

Protection from Discrimination. Licensees may not discharge, discriminate against, or otherwise retaliate against any worker who exercises rights under Part 19 — including raising safety concerns, requesting records, or participating in an NRC inspection. Discrimination for these activities is a federal violation.

Safety Culture Connection

The principles in Part 19 are foundational to nuclear safety culture. The NRC's safety culture policy statement identifies a questioning attitude and free flow of safety information as essential traits of a healthy nuclear workplace. Part 19 is the legal framework that makes those traits enforceable. When workers know they can report concerns without fear of retaliation and can verify their dose records, the entire facility operates more safely. As a future nuclear plant technician or operator, you are both a beneficiary and a steward of these rights.

Lockout/Tagout and PPE reminder: While Part 19 addresses radiation protection rights, remember that when you physically work in radiation areas, you must also follow lockout/tagout procedures for energized equipment (per OSHA 29 CFR 1910.147 or the plant's equivalent procedure) and wear all required PPE — dosimetry, appropriate respiratory protection, anti-contamination clothing, and any other protection specified by the Radiation Work Permit for your task. Part 19 does not replace operational radiation protection procedures; it complements them.

The Worker Notification Memo in Practice

A site-level worker notification memo is a document a licensee issues to workers to communicate radiation-related information required by Part 19. A compliant memo must:

1. Identify the specific hazard or information being communicated.

2. State the applicable protective measures or precautions.

3. Reference the relevant procedures or regulatory requirements.

4. Provide a point of contact (usually the Radiation Protection department).

5. Be written in plain language that any affected worker can understand.

When you draft such a memo in your activity today, compare every element against the Part 19 checklist. If any required element is missing, the document is noncompliant — even if everything else is accurate.
