      Why Regulators Are Cracking Down on Dosimetry Violations

      Dosimetry compliance is receiving increased attention from regulators. Below are three common questions about dosimetry compliance, along with steps organizations can take to stay audit-ready. 
       
      What is the most common dosimetry violation? 
      The most frequent dosimetry violation is failure to issue or properly use personal dosimeters for workers likely to receive 10% or more of the regulatory dose limit. This also includes lack of objective evidence, such as area monitoring that confirms worker and public exposure levels remain within regulatory limits.
       
      Which agency regulates radiation monitoring in the United States? 
      The U.S. Nuclear Regulatory Commission (NRC) was established by Congress in 1974 as an independent agency tasked with ensuring the safe use of radioactive materials for beneficial civilian purposes, while also protecting people and the environment.

      The NRC is not the only agency involved in radiation monitoring. While the NRC regulates the use of radioactive materials, X-rays and other X-ray generating devices are typically regulated at the state level. The Occupational Safety and Health Administration (OSHA) also establishes workplace safety standards related to ionizing radiation.

      What are the duties of a Radiation Safety Officer? 
      A Radiation Safety Officer (RSO) is legally required for any facility licensed to use radioactive materials under NRC regulations, with X-ray devices regulated separately at the state level. 
      The RSO is responsible for implementing, coordinating and supervising the organization’s radiation safety program. This includes ensuring compliance with federal, state and local regulations and enforcing radiation safety policies and procedures across the organization. 

      The role typically includes oversight of monitoring programs, maintenance of exposure records and ensuring employees follow established radiation safety practices. 

      Key notes  
      Dosimetry monitoring failures come at a great cost. Regulatory bodies are imposing civil penalties ranging from $9,000 to $45,000. 
       
      Veterinary hospitals can reduce risk by keeping several priorities in focus: 
      • Understand applicable regulations: Monitoring programs must meet national, state and local requirements. 
      • Stay audit-ready: Maintain proper dosimeter issuance, monitoring programs, documented procedures, training and records. 
      • Evaluate potential violations: Serious compliance issues often include failure to issue or use personnel dosimeters, using inappropriate dosimeters for the type of radiation, failing to maintain exposure records or failing to properly monitor staff exposure. 
       
      Proactive radiation safety programs help mitigate risk, promote compliance and protect clinics from fines and service disruptions. 
       
      Final takeaway: Go beyond the bare minimum 
      Although sometimes considered administrative, dosimetry violations are increasingly being treated by regulators as programmatic safety failures. Companies that fail to issue badges, monitor exposures, return dosimeters on time or maintain proper records may face costly civil penalties for significant or systemic failures – including veterinary facilities. 
       
      Implementing a comprehensive, well-documented, reviewed and auditable dosimetry program goes beyond compliance. It helps protect workers, manage risk and safeguard your license.

      Proactive radiation safety is the most effective strategy for avoiding costly dosimetry violations, and it begins with a reliable dosimetry program. Patterson partners with the Radiation Detection Company

      Audit-readiness: Fostering a culture of compliance 
      Ensure your practice's dosimetry program is audit-ready by following these five steps. 
       
      1. Ensure proper dosimeter issuance and usage 
      Issue a personal dosimeter (i.e., OSL, TLD, or NetDose) to workers likely to receive 10% or more of the occupational radiation dose limit and enforce policies requiring badges to be worn correctly and exchanged on time. Personnel and supervisors should be trained on dosimeter policies and the consequences of non-use. 
       
      1. Maintain monitoring records and exposure reports 
      Retain exposure records and dosimeter results according to regulatory requirements. Establish a centralized record-keeping system with secure access and a clear audit trail of issuance, retrieval, processing and results. 
       
      1. Conduct periodic reviews and gap analysis 
      Perform internal audits of badge issuance rates, unmonitored workers and exposure trends. Regularly review radiation safety program materials, including training records, policy acknowledgements and corrective actions. 
       
      1. Develop clear procedures and accountability 
      Maintain written procedures for dosimeter issuance, lost/damaged badges, high-exposure investigation and supervisor oversight. Clearly document roles and responsibilities across the program. 
       
      1. Stay prepared for inspection or enforcement 
      Maintain an audit-readiness binder or digital folder containing personnel badge assignments, worker exposure summaries, training records, lost badge logs, audit reports and corrective actions. Running “what if” scenarios such as lost badges or unusual exposure trends can help identify compliance vulnerabilities before inspections occur.
