Radiation plays an essential role in modern research and diagnostics—from tracer studies in biology and medicine to X-ray analyses in materials science. With its benefits, however, come some inherent risks. Managing those risks requires collaboration between two key roles in any laboratory that handles radioactive materials or radiation-generating devices: the lab manager and the radiation safety officer (RSO).
Together, these professionals form the foundation of a laboratory’s radiation protection program. Their partnership—when built on clear communication and shared accountability—helps ensure compliance, minimize exposure, and foster a culture of safety that protects both people and science.
Distinct but complementary roles
The RSO oversees all aspects of radiation protection and regulatory compliance. A new RSO requires significant training to understand the health effects, regulatory requirements, security, and development of radiation safety programs. This training is readily available and often takes up to 40 hours to complete, and comes with a certificate enabling the RSO to meet compliance requirements. The RSO’s duties often include:
- Maintaining the institution’s radioactive materials license and ensuring compliance with local, state, and federal regulations.
- Developing and enforcing radiation safety policies and procedures.
- Conducting exposure monitoring and contamination surveys.
- Overseeing personnel dosimetry and maintaining exposure records.
- Training staff in safe radiation practices and emergency procedures.
- Investigating incidents or near-misses involving radioactive materials or radiation-producing equipment.
- Ensuring the security of any radioactive devices or materials in the lab.
- Manage the proper disposal of radioactive materials.
The lab manager, by contrast, is accountable for day-to-day operations within the laboratory. Their role focuses on ensuring individual health and safety, as well as developing a safety culture. They may appoint a lab safety manager to take responsibility for developing the details of the lab safety program, including ensuring staff follow the RSO’s guidance. Core accountabilities include:
- Ensuring all lab activities involving radioactive materials or radiation sources are authorized and properly documented.
- Verifying that lab personnel complete the required training before working with radiation.
- Maintaining inventory and usage logs of radioactive materials or radiation-producing equipment.
- Providing the necessary PPE and engineering controls to limit exposure.
- Reporting any unsafe conditions, spills, or exposures promptly to the RSO.
In short, the RSO sets the framework; the lab manager ensures its proper execution.
Building alignment through communication
Misalignment between these two roles can undermine even the most robust safety program. The key to avoiding that gap is proactive and consistent communication. Successful collaboration often includes:
- Regular check-ins: Routine meetings between the RSO and lab manager ensure that any new experiments involving radiation sources are reviewed for potential safety implications before work begins.
- Joint risk assessments: When developing new protocols involving radiation, the RSO and lab manager should assess potential exposure scenarios together, identifying where engineering controls, shielding, or procedural changes can reduce risk.
- Shared training responsibilities: While the RSO typically provides technical instruction on radiation safety, the lab manager reinforces these principles during onboarding, daily supervision, and performance evaluations.
- Clear documentation: Accurate and accessible records—of training, surveys, and material inventories—support both compliance and transparency. Shared digital systems or dashboards can streamline this process.
Effective communication between the RSO and the lab manager also sets the tone for the staff. When employees see both roles engaged and aligned, it reinforces the expectation that radiation safety is everyone’s responsibility.
Practical strategies for radiation safety
The principles of radiation safety rest on three core concepts: time, distance, and shielding. Lab managers and RSOs should work together to translate these principles into practical procedures:
- Use shielding: Ensure the correct type and thickness of shielding—lead for gamma rays and X-rays, Plexiglas or acrylic for beta particles—is in place. Inspect shielding regularly for cracks or degradation.
- Minimize time: Encourage staff to plan experiments carefully to limit time spent near radiation sources. Dry runs and checklists can reduce errors and unnecessary exposure.
- Maximize distance: Use tongs, remote handling tools, and barriers to increase distance from radiation sources wherever possible.
Beyond these fundamentals, additional best practices include:
- Routine surveys: Perform contamination checks and area monitoring at a frequency appropriate to the work being conducted. Immediate cleanup of small spills prevents larger incidents.
- Access control: Restrict entry to radiation areas to trained and authorized personnel. Use clear signage and labeling to mark controlled zones.
- Equipment maintenance: Calibrate detectors, survey meters, and dosimetry badges regularly. Faulty instruments can create a false sense of security.
- Emergency preparedness: Establish and practice spill and exposure response procedures. Everyone in the lab—not just radiation workers—should know what to do if an alarm sounds.
- Continuous education: Provide refresher training annually and whenever new technologies or regulations are introduced.
Cultivating a safety culture
A strong radiation safety culture depends on trust and collaboration. The RSO brings technical expertise and regulatory insight; the lab manager provides operational oversight and leadership. When these strengths are combined, the result is a safer, more efficient laboratory.
Encourage open reporting of near-misses or safety concerns without fear of reprisal. Small mistakes, when discussed openly, often provide the best learning opportunities. Recognize and reward safe behaviors to keep radiation safety visible and valued.
