7 Ways to Minimize Radiation Exposure

By September 19, 2023April 1st, 2024No Comments

Limiting occupational radiation exposure is paramount for worker safety. The ways to minimize radiation exposure encompass time management, protective measures, training, and safety protocols. These combined behaviors and strategies play a pivotal role in safeguarding individuals working in radiologic environments.

The use of radiation contributes to numerous medical, scientific, and industrial advancements. Its diverse applications include medical diagnosis and treatment, industrial processes like flaw detection, energy generation in nuclear power plants, and research in fields such as physics, biology, and materials science. 

A bustling radiology department is a prime example. Here, dedicated radiologic technologists meticulously calibrate equipment to restrict radiation output while maintaining diagnostic quality. They employ shielding and personal protective equipment to tailor protection to individual needs. Read on to discover their seven fundamental practices for minimizing radiation exposure.


What Is Normal Radiation Exposure?

Normal radiation exposure refers to the typical background radiation that humans encounter during their daily activities. On average, people are exposed to about 2–3 mSv (millisieverts) annually. Radiation exposure within these normal levels is harmless. Below is a table showing the primary sources of natural radiation.


What Is Normal Radiation Exposure?
Natural Radiation Source Typical Dosage Range

(in mSv per year)

Gamma rays from the ground 0.3–0.6
Cosmic rays from space 0.3–1.0
Radon and thoron gas from rocks and soil 0.2–1.0
Radionuclides such as potassium, carbon, and radium in food 0.2–0.8


Normal occupational radiation exposure levels depend on the industry and job tasks involved. Regulatory standards establish safety limits for occupational radiation exposure. In the United States, the overall dose limit for radiation workers is 50 mSv per year. Special limits apply to specific body parts, such as the lens of the eye.


The 7 Most Effective Ways of Limiting Occupational Radiation Exposure

A question often asked is, “What is the correct practice for minimizing exposure?” The answer is that a synergistic combination of behaviors and strategies maximizes safety.

Here are seven effective ways to achieve safety in the radiologic workplace.


#1. The ALARA Principle – Time, Distance, and Shielding

Implement ALARA – As Low As Reasonably Achievable by practicing the three things we use to help minimize radiation exposure: 

  • Minimize time: Reduce the time workers spend near radiation sources to the necessary minimum.
  • Increase distance: Maintain a safe distance from radiation sources. Use remote controls to activate X-ray beams or long-handled tools to transfer radioactive materials.
  • Use shielding: Install shielding materials and barriers. Ensure workers wear appropriate personal protective equipment (PPE), such as lead aprons, gloves, and eyewear.


#2. Dose Optimization

Optimize the patient dose in interventional radiology to protect both the patient and the operator:

  • Calculate minimum dose: Tailor the dosage to individual patient characteristics such as weight and size.
  • Limit the target area: Reduce the region of a scan or X-ray to the smallest possible area.


#3. Radiation Monitoring and Dosimetry

Use monitoring devices in the workplace, such as dosimeters and radiation detectors:

  • Ensure compliance: Track individual exposure with personal dosimeters to comply with established dose limits.
  • Review monitoring data: Identify trends or areas with higher radiation levels and take corrective actions.


#4. Training and Education

Provide comprehensive training to all personnel who work with or near radiation sources.

  • Ensure workers understand the hazards: Use simulations to emulate safe practices and implement drills of emergency procedures.
  • Conduct refresher training sessions: Procedural knowledge must be kept up-to-date.


#5. Administrative Controls

Establish clear policies and procedures for radiation safety and adherence to regulations: 

  • Institute access control: Entry to the radiological controlled area should be limited to authorized personnel.
  • Develop a safety program: Develop robust radiation protocols with designated responsible individuals and committees.


#6. Inspection and Maintenance

Minimize the risk of equipment malfunctions and accidental exposure through regular, documented inspections and maintenance according to local regulations and guidelines:

  • Check radiation-emitting equipment: Calibration and the inspection of collimators, exposure timers, and safety features should be performed by a qualified technician.
  • Check PPE: Regularly inspect radiation-protective garments and accessories for signs of damage, including cracks, tears, or thinning. Replace any damaged items promptly.


#7. Radiation Safety Culture

Foster a strong workplace culture that emphasizes the importance of radiation safety:

  • Report safety concerns: Implement procedures for staff to convey their concerns about safety issues.
  • Promote a proactive approach: Encourage staff to put safety first.
