What Does a Radiation Safety Technician Do?
You cannot see, hear or smell radiation, so someone has to measure it. Radiation safety technicians do that measuring at nuclear plants, hospitals, labs and cleanup sites, surveying work areas, taking air and wipe samples and marking where people can go and how long they can stay.
Also known as: Radiation Control Technician, Senior Radiation Control Technician
Radiation Safety Technician Duties and Responsibilities
The primary responsibilities of a radiation safety technician include:
- Survey work areas with dose-rate meters and contamination monitors, and post the levels at entrances.
- Take air samples and swipe samples, and count them on the lab's detectors.
- Cover high-dose jobs in person, timing each worker's stay and moving people when readings climb.
- Set up barriers, signs and step-off pads that mark contaminated zones.
- Scan workers and tools leaving controlled areas and decontaminate anything that fails.
- Calibrate and source-check portable instruments and tag any that fall out of tolerance.
- Package radioactive waste for shipment and complete the transport paperwork.
- Exchange dosimeters, log readings and flag workers approaching their dose limits.
- Write up surveys and job coverage in the site's radiation protection records.
- Guide newer technicians during plant outages and large cleanup jobs in senior grades.
Required Skills and Qualifications
To succeed as a radiation safety technician, you will need the following skills and qualifications:
- Radiation detection and survey instruments
- Contamination control and decontamination methods
- NRRPT registration for senior roles
- Basic math for dose, time and distance calculations
- Careful, legible survey records
- Comfort wearing respirators and protective suits
- Willingness to work shifts and travel for plant outages
- Steady nerves when a reading jumps
Education and Training
Radiation safety technicians usually learn through on-the-job training after high school or military service, but some start out by earning an associate's degree in radiation protection or nuclear technology. Plants often run their own qualification programs. Senior technicians can take on crew leadership or move into specialist roles with more schooling.
Salary and Job Outlook
Typical pay: $52,470 - $78,850 per year, with a median of $61,560.

BLS projects employment of occupational health and safety technicians, the group this job belongs to, to grow about 19 percent from 2025 to 2035. Across the group, BLS expects about 3,800 openings a year. Radiation work is one slice of that group, and technicians willing to travel for plant outages and decommissioning jobs tend to find the steadiest demand.
