Our Goals and Vision

Radiation in Space. An in-depth look at MIRD. What is radiation safety and why is it important? Every month, Versant Physics’ host Dr. Eric Ramsay converses with leading experts in the healthcare, medical and health physics, and radiation safety fields. We dive into the important topics that make up our industry’s current culture and showcase the impact the field has on the world. We hope that these conversations will inform, inspire, and educate our listeners.

    Eric and Alan present an excellent discussion about a very important, controversial subject. Alan’s review of the historical development of this policy-making model, and its current impact are highly illuminating. While the model was a good start for developing safe radiation practice, it is clear that we need to advance and develop a better understanding of the effects of low doses of radiation. Alan makes a very good argument for the serious limitations of relying on a “conservative” approximation to low dose effects. The scientific community needs to improve low dose models and better educate people about the risks associated with low doses of radiation. In addition to the problems that Alan mentioned, there is also the clinical issue of therapeutic abortions, which are often done simply because a relatively safe diagnostic X-ray procedure was performed. The LNT model and the ALARA principle do not enhance scientific understanding of low dose radiation risk or help individuals develop a rational, balanced perception of radiation risk.

    Great podcast!

Dr. Alan Fellman, Ph.D., CHP

Dade Moeller nv5, Manager for Commercial Consulting

EXPERIENCE OVERVIEW

Alan Fellman earned a doctorate degree in Radiological Studies from New York University in 1989 and attained certification in Comprehensive Health Physics from the American Board of Health Physics in 1995. He has spent the bulk of his career providing radiation safety training and consulting services to a variety of commercial and public sector clients. He is a senior health physicist with NV5 Dade Moeller and a member of the Dade Moeller Training Academy faculty. Dr. Fellman’s consulting experience includes preparation of radioactive materials license applications and written radiation safety programs for numerous NRC and Agreement State licensees, design of final status surveys in support of decommissioning, and conduct of comprehensive radiation safety program compliance audits. He has also provided litigation support to several clients, serving as an expert witness in law suits which included allegations related to radiation-induced health effects.

Permits

THE PERMISSION SYSTEM FOR INVENTORY TRACKING, MACHINE MANAGEMENT & EQUIPMENT CATALOG MODULES

Permit Profile

Each permit has a dedicated profile of information that includes authorized personnel, radioactive material, machines, and devices. Permit conditions, completed audits, and forms are also found on this profile.

Authorized Condition Database

Create and view authorized conditions included on permits. Previously created authorized conditions are listed with their code, category, and description.

Permit Enforcement

Information specified on a permit not only serves as a record of that permit, but also controls what can be added to other modules. The location, owner and type of radioactive materials, machines, and equipment can be enforced by permits.

Permit Audits

Perform permit audits, mail the results to relevant personnel, and track responses to non-compliances.
