Overview

A Radiation Health Technician conducts radiation monitoring and surveys, analyzes gases and liquids, and considers the medical effects of ionizing radiation exposure. The technician directs the personnel dosimetry program, maintains radiation exposure information in health records, and generates radiation reports.

Minimum clearance: Secret

Core Skills

  • Personnel dosimetry program administration
  • Gas and liquid sample analysis
  • Radiation exposure health record maintenance

Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Nuclear Monitoring Technicians

Radiation surveys, personnel exposure monitoring, and dosimetry program administration directly overlap with nuclear workplace monitoring.

How to prepare: Prepare a sample exposure-monitoring report using fictional data to demonstrate how you would track readings and flag exposures approaching specified limits.

What the civilian work involves
  • Monitor personnel to determine the amounts and intensities of radiation exposure.
  • Inform supervisors when individual exposures or area radiation levels approach maximum permissible limits.
  • Brief workers on radiation levels in work areas.
Civilian tools and software (examples)
  • Microsoft Excel

Occupational Health and Safety Technicians

Workplace radiation surveys and exposure recordkeeping transfer to occupational hazard testing and safety documentation.

How to prepare: Take a course covering hazardous materials and workplace safety regulations to broaden your radiation-focused experience to other occupational hazards.

What the civilian work involves
  • Test workplaces for environmental hazards, such as exposure to radiation, chemical or biological hazards, or excessive noise.
  • Maintain all required environmental records and documentation.
Civilian tools and software (examples)
  • Microsoft Excel

Environmental Science and Protection Technicians, Including Health

Gas and liquid analyses and radiation reporting provide a foundation for environmental sample testing and test-result documentation.

How to prepare: Complete practical training in environmental sample collection and preparation to extend your analysis experience to pollution-monitoring work.

What the civilian work involves
  • Collect samples of gases, soils, water, industrial wastewater, or asbestos products to conduct tests on pollutant levels or identify sources of pollution.
  • Record test data and prepare reports, summaries, or charts that interpret test results.
  • Prepare samples or photomicrographs for testing and analysis.
Civilian tools and software (examples)
  • Microsoft Excel
