Radon is a radioactive gas that occurs naturally from the decay of uranium in soil and rock. Since radon is colorless, odorless, and tasteless, it can go undetected without the proper tools. Long-term exposure to elevated levels of radon is linked to lung cancer, making it a significant health concern. Radon measurement professionals (RMP) play a critical role in identifying the presence of this hazardous gas, especially in homes and buildings where radon can accumulate to dangerous levels.
In Minnesota, the demand for radon professionals is growing due to increased public awareness and regulations. If you’re considering becoming a radon measurement professional in Minnesota, there are several steps and requirements you must follow, including state certifications, education, equipment management, and ongoing continuing education units (CEUs). Here’s a comprehensive guide on how to enter the field and maintain your standing as a professional radon measurement technician in Minnesota.
1. Initial Certification: Becoming a Licensed Radon Measurement Professional
The first and most important step to becoming a radon measurement professional in Minnesota is obtaining certification. In Minnesota, all radon professionals must be licensed by the Minnesota Department of Health (MDH), as the state mandates strict compliance to ensure that professionals are trained and knowledgeable in radon testing. The process includes:
Pre-Licensing Education Before applying for licensure, you must complete a state-approved radon measurement training course. These courses are typically offered by recognized radon organizations such as the National Radon Proficiency Program (NRPP) or the National Radon Safety Board (NRSB). The coursework generally covers the principles of radon, measurement techniques, health risks, state regulations, and equipment use.
Exam Requirement After completing the training, you must pass a national certification exam to demonstrate your proficiency in radon testing methods. The exam assesses your understanding of radon, testing protocols, and proper device placement. Both the NRPP and NRSB offer certification exams that are recognized by the MDH. This is a 4 hour proctored exam that covers all aspects of radon measurement, i.e. the test procedures, the measurement techniques, report writing, quality program, etc.
Application Process. Once you have passed the exam, you can apply for your radon measurement professional license through the MDH. This application involves submitting proof of training, exam results, and an application fee. As part of the process, you must also agree to adhere to Minnesota’s radon measurement standards and provide evidence of the equipment you will use.
2. Continuing Education Units (CEUs)
Obtaining your radon measurement professional license is not the end of the journey. As technology and research on radon evolve, it’s critical to stay updated on the latest practices and regulations. Minnesota mandates that all licensed radon professionals participate in continuing education to maintain their license.
CEU Requirements. Radon professionals in Minnesota are required to complete 8 continuing education units (CEUs) every year. CEU courses must be approved by a recognized radon certification body, such as the NRPP or NRSB. These courses focus on advanced topics in radon testing, new measurement technologies, regulatory updates, and proper mitigation methods. The courses are designed to ensure that professionals stay current with industry standards and best practices.
Renewal Process In addition to CEUs, professionals must renew their license every year. This requires submitting documentation of the completed continuing education credits, as well as an application and renewal fee to the MDH. Failure to complete CEUs or renew the license can result in suspension or revocation of your certification.
Equipment Calibration and Maintenance One of the most important aspects of radon measurement is the reliability and accuracy of the equipment used. In Minnesota, licensed radon measurement professionals must follow strict guidelines to ensure that their testing devices are properly maintained and calibrated.
Types of Equipment Common types of radon measurement devices include continuous radon monitors (CRMs), electret ion chambers, charcoal canisters, and alpha track detectors. Regardless of the type of device used, it is essential that it provides accurate readings, as inaccurate measurements can lead to serious health risks.
Calibration Requirements In Minnesota, it is mandatory that all continuous radon monitors and other electronic measurement devices be calibrated at least once every 12 months. Calibration ensures that the device remains accurate and reliable over time, providing homeowners and property managers with valid radon readings. Calibration must be performed by a qualified calibration laboratory, and the radon professional must keep detailed records of each calibration.
Maintenance In addition to regular calibration, radon professionals are responsible for ensuring that their equipment is maintained in proper working order. This includes regular inspections, testing of sensors, and replacing batteries as needed. If a device is not functioning correctly, it must be repaired or replaced before being used in a client’s home or building.
Record-Keeping Minnesota requires that radon professionals maintain detailed records of all equipment calibrations and repairs. These records must be readily available for review by the MDH upon request. Failure to maintain proper documentation could result in penalties or loss of certification. Random audits by the MDH are a way of ensuring that all measurement professionals are adhering to the regulations.
4. Adhering to Minnesota’s Radon Testing Protocols
Beyond training, CEUs, and equipment calibration, radon professionals in Minnesota must adhere to specific testing protocols established by the MDH. These protocols are in place to ensure consistency and accuracy across all radon measurements performed in the state.
Test Duration According to MDH guidelines, short-term radon tests must be conducted for at least 48 hours. During this time, the building must remain under closed conditions, meaning that windows and doors should be kept shut as much as possible, among other requirements.
Test Placement Proper placement of radon measurement devices is critical. In Minnesota, testing should be conducted in the lowest level of the building that could be occupied, such as a basement or first floor. The device must be placed away from drafts, high humidity areas, and direct sunlight.
Written Reports A formal report must be published and kept for 6 years after the test was completed. It will include test conditions, the result, and a recommendation for mitigation if the data warrants. This data must also be inputted online with an MDH database.
Follow-Up Testing If initial radon levels are found to be elevated, follow-up testing is often recommended to confirm the results. In many cases, long-term radon tests (lasting 90 days or more) are used to provide a more accurate reading of the average radon levels over time.
Becoming a licensed radon measurement professional in Minnesota has been a rewarding career choice in my retirement, but it comes with strict requirements and responsibilities. From completing the initial training and passing a national exam, to maintaining CEUs and ensuring my equipment is properly calibrated, you must stay on top of regulations and best practices to protect public health. By adhering to these requirements and keeping up with advancements in the field, I provide accurate radon testing services and contribute to the safety and well-being of Minnesota’s residents. Consider getting your house tested this year.
