Dr. Darrell Fisher papers published ahead of print in The Radiation Safety Journal

Dr. Darrell Fisher
Dr. Darrell Fisher, Nuclear Medicine Physicist with Versant Physics, recently had two papers published ahead of print in Health Physics, the Radiation Safety Journal.
The first, titled “Patient-Specific Extravasation Dosimetry Using Uptake Probe Measurements” was co-authored by Dr. Fisher, Dr. Dustin Osborne, Jackson W. Kiser, Josh Knowland, and Dr. David Townsend. It addresses the common problem of extravasation in radiopharmaceutical administration and how it can result in significant radiation dose to underlying tissue and skin. According to the paper’s abstract, “The resulting radiation effects are rarely studied and should be more fully evaluated to guide patient care and meet regulatory obligations. The purpose of this work was to show that a dedicated radiopharmaceutical injection monitoring system can help clinicians characterize extravasations for calculating tissue and skin doses.”
The second paper “Radiation Safety for Yttrium-90-polymer Composites (RadioGelâ„¢) in Therapy of Solid Tumors” was written solely by Dr. Fisher and focuses on demonstrating the radiation safety of the injectable Yttrium-90-polymer therapeutic agent. According to the abstract, “Safety in the patient is defined by its ability to target precisely and remain confined within tumor tissue so that radiation doses are imparted to the tumor and not to normal organs and tissues.”

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.
