Training empowers your staff, providing them the confidence to carry out their duties. We can provide lectures or hands-on training to individuals, groups, or to organization meetings. We can use your materials or subject matter prepared by CHP Consultants.
Typical training sessions are outlined below. They can be adapted to suit your needs regardless of your dosimetry vendor. Suggestions of new topics are always welcome.
Radiation Safety Officer or Basic Health Physics Course
This is a 40-hour course on health physics for new RSOs or as part of a general training program. This course focuses on radiological fundamentals to help RSOs get a good understanding of health physics. This allows them to adapt to new situations by understanding the fundamental concepts of dosimetry, instrumentation, regulations, radiation biology, natural radiation, etc. RSOs will gain knowledge about how the key concepts of fit together.
Film is the most commonly used dosimeter material in the United States and the world. Like other dosimeters using a sensitive medium with a high effective Z, film dosimeters are very sensitive to low-energy photons. This characteristic makes film an excellent dosimeter for low dose applications. If film is processed using incorrect assumptions, significant errors in dose estimation may result. This problem is common in X-ray environments, especially fluoroscopy.
This lecture will enable your staff to understand the use cycle of film dosimeters and their inherent strengths and weaknesses. The performance and operating characteristics of typical film dosimeters are discussed using real data and sample dosimeters. Dosimeter processing and typical quality control measures are discussed in the context of their influence on the resulting measured dose. This lecture will help improve the dosimeter performance at your facility and will yield more accurate and lower doses.
Thermoluminescent Dosimetry (TLD)
TLD material stores energy from incident radiation by trapping energized electrons. This stored energy is released to determine the dose received. Many TLDs are relatively energy independent and are useful for monitoring radiation dose in mixed fields (gamma, X-ray, beta and neutron). The operational characteristics and design of TL dosimeters (multi-element, extremity) are discussed with an emphasis on dosimeters used at your facility. Quality control methods for your facility and those employed by dosimetry vendors are presented along with practices and applications that improve performance. Also discussed are the characteristics of each dosimeter material and the associated limitations of use.
Training Lecture on track-etch dosimetry (CR-39)
Damage sites, or "tracks," created by incident recoil particles (from neutrons) or direct damage (from alpha particles), are used to indicate dose with CR-39 dosimeters. The tracks are read after the damage sites are developed through a chemical etching process. These dosimeters are relatively energy independent for fast neutrons, but insensitive to thermal neutrons. Operational characteristics of CR-39 are discussed in addition to quality control methods employed in the reading process.
Training on other Topics
Health physics is a multifaceted, dynamic field, so we never get bored. The field encompasses understanding biological effects and communicating relative risks, analyzing radiation dosimetry, understanding radiological fundamentals, using instrumentation, analyzing air sampling, etc. Combinations of the above and other topics are available. Call or email with your requests and suggestions.
- A knowledgeable workforce is more productive and less likely to overextend him/herself.
- Training raises the confidence of your staff.
- Training relieves undue fear associated with radiation and brings the relative risks to light.
