Radiation in Space

Episode 1 | recorded November 11, 2019

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.

Dr. Ron Turner

NIAC Senior Science Advisor


Dr. Turner is an internationally recognized expert in radiation risk management for astronauts, particularly in response to solar storms. For the past eight years he served as Principal Investigator on NASA research grants investigating risk management strategies for solar particle events during human missions to the Moon or Mars. He is a Participating Scientist on the Mars Odyssey program, where he is working with data from the MARIE radiation monitoring experiment. He has frequently been an invited participant at NASA workshops looking at Space Radiation/Biology Missions, Life Science mission requirements for Mars 2001 and 2003, and Solar Particle Event impact on design of human missions. He served on a National Research Council Committee looking at precursor measurements necessary to support human operations on the surface of Mars (results published in May 2002). He was an invited witness to the Presidential Moon Mars and Beyond Commission in 2004. He supported a 1999 National Academy of Sciences study of the impact of Solar Particle Events on the construction of the International Space Station.

Dr. Turner has over thirty years experience in space systems analysis, from requirements definition to system architecture evaluation. He has developed expertise in orbital mechanics, sensor design, and spacecraft design.

Dr. Turner’s Ph.D. is a multi-disciplinary degree covering Nuclear/ Particle/ Astrophysics.

Forum Article "Radiopharmaceutical Extravasation: Pragmatic Radiation Protection" published ahead of print

An article written by Versant team members Dr. Darrell R. Fisher, Ph.D. and Misty Liverett, M.S., CNMT was recently published ahead of print in Health Physics. The article provides an unbiased, scientific assessment of pragmatic and reasonable health physics actions that should be taken in response to inadvertent extravasation events.

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.
