Health physics technicians, also known as nuclear monitoring technicians, survey a workplace or other areas that may expose people to radiation to assess whether there is radiation or other hazardous materials present. Many health physics technicians work at universities or medical centers where radioactive material is used for research or to treat patients. They also work at nuclear power plants and other facilities that produce radioactivity or may monitor exterior areas that may have been exposed to radiation to develop a decontamination plan. As a health physics technician, your job duties include testing an area for radioactivity by sampling air, water, gases, or solids in the area, evaluating acceptable exposure limits, and training workers on proper safety protocols related to radioactive exposure.
