Health Physicist
This role is for individuals passionate about applying physics principles to ensure safety in environments involving radiation. It offers the profound satisfaction of protecting public health and occupational workers, but demands meticulous attention to detail, strict adherence to regulations, and a strong sense of responsibility.”
About This Role
Focuses on the science of radiation protection, evaluating dose limits and environmental radiation levels.
A Day in the Life
A Health Physicist focuses on radiation protection. Their day involves evaluating radiation safety programs, conducting risk assessments in medical and industrial settings, calibrating radiation detection equipment, and ensuring compliance with national and international radiation safety standards. They educate staff and develop emergency response plans.
- Conduct radiation surveys and measurements in hospitals (radiology, nuclear medicine, radiotherapy) and industrial facilities
- Develop and implement radiation safety programs and procedures
- Perform dose calculations and assessments for occupational workers and the public
- Calibrate and maintain radiation detection and measurement equipment
- Provide radiation safety training to medical staff, researchers, and industrial workers
- Ensure compliance with national regulatory requirements (e.g., Atomic Energy Board of Sri Lanka) and international standards
- Investigate radiation incidents and develop corrective actions
- Advise on shielding design for new radiation facilities
Work Environment
Works in a hybrid environment, splitting time between office-based analysis and field work in hospitals, research labs, or industrial sites where radiation sources are present. Requires careful adherence to safety protocols and attention to detail.
Typical hours: 40h/week · WLB score 7/10 · OCCASIONAL overtime
Generally standard hours, but emergency response to radiation incidents or urgent safety assessments can require irregular hours. Travel to different sites is also common.
