John Till was selected to be a member of the newly formed NCRP Scientific Committee 1-25. The committee is charged with preparing an NCRP Commentary on “Recent Epidemiologic Studies and Implications for the LNT Model”. The work is supported by the US NRC. The committee will look at recent literature related to low dose exposures to determine the continued appropriateness of the LNT model for radiation protection. John will be assisted by RAC team members Helen Grogan and Harold Beck in evaluating the dosimetry used in the epidemiologic studies being evaluated.
Members of NCRP SC 1-25 shown above include (left to right, beginning with top row):
John D. Boice, Jr., cochair (NCRP)
Lawrence T. Dauer, cochair (Memorial Sloan Kettering Cancer Center)
Scott Davis (Fred Hutchinson Cancer Research Center)
Fred A. Mettler, Jr. (University of New Mexico)
R. Julian Preston (U.S. Environmental Protection Agency, retired)
Roy E. Shore, cochair (Radiation Effects Research Foundation, retired)
John Till attended a meeting of NCRP Council Committee 1 (CC-1) in December 2015 at NCRP headquarters in Bethesda, MD. CC-1 was formed in early 2014 to write an NCRP report updating and expanding on NCRP Report No. 116, Radiation Protection Guidance for the United States, which was published in 1993. Substantial advances in radiation effects knowledge, as well as radiation protection understanding and culture, have occurred, and the new report will serve as an update.

RAC team members Jim Rocco, Justin Mohler, Mark Packard, Helen Grogan, Art Rood, and Lane Urtel (shown above, left to right) gathered at the ddms, inc., offices in St. Paul, Minnesota, from December 9 through 11, 2015, to discuss and finalize plans for a number of upgrades to the RACER suite of tools. The upgrades that are being implemented include:
NEW multi-client server setup for RACER web hosting
NEW dashboard user interface with multi-facility capabilities for RACER Data Analysis Tool
NEW web-accessible dose-based compliance system functionality in RACER Data Analysis Tool and Risk Calculation Tool
Helen Grogan and John Till enjoyed being guided by the father of radioecology, Professor F. Ward Whicker, Colorado State University, on an ecological fact finding and snowshoeing adventure in Rocky Mountain National Park.
Helen Grogan met with members of the National Council on Radiation Protection and Measurements (NCRP) Scientific Committee 3-1 on Emergency Response Dosimetry in Norwich, CT, during the week of November 16, 2015. The committee discussed its work at the New England Radiological Health Conference in Norwich, as part of the committee’s stakeholder engagement efforts. Helen also had the opportunity to check out the controls of a P-47 Thunderbolt at the “Night at the Museum”, hosted by the New England Air Museum for the New England Radiological Health Conference.

Mr. Art Rood attended a meeting in Oslo, Norway, during the week of November 16, 2015, with ICRP Task Group 98, Application of the Commission’s Recommendations to exposures resulting from contaminated sites from past industrial, military, and nuclear activities. The mandate of the task group is to develop a report that describes and clarifies the application of the Commission’s Recommendations on radiological protection of workers, the public, and environment to exposures resulting from sites contaminated due to past industrial, military, and nuclear activities.

Team members gathered during the week of November 9, 2015, for RAC’s annual fall meeting at Kiawah Island, South Carolina. The meeting provided a valuable opportunity for the team to evaluate progress on all ongoing projects, discuss technical issues in depth, and make plans regarding both ongoing and future work.
Dr. John Till attended a meeting on November 3 and 4, 2015, in Oak Ridge, Tennessee, with NCRP Scientific Committee 6-9, “Deriving Organ Doses and Their Uncertainty for Epidemiologic Studies”. The committee’s objective is to prepare a report on dosimetry related to reconstruction of doses for epidemiology. The dosimetric issues involved are complex and differ among the varied exposed populations under evaluation: atomic veterans, DOE workers exposed to both penetrating radiation and intakes of radionuclides, nuclear power plant workers, medical radiation workers, and industrial radiographers. The NCRP report is envisioned to cover the specifics of practical dose reconstruction for the ongoing epidemiologic studies with uncertainty analysis evaluation.
Helen Grogan was a Member of the United States Delegation to the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) at the Sixty-Second Session of the Committee, which met in Vienna, Austria, from June 1 – 5, 2015. Attendees pictured above are (L-R): Armin Ansari, Bruce Napier, Helen Grogan, Wesley Bolch, Gayle Woloschak, Julian Preston, Naomi Harley, Vincent Holahan, and Lynn Anspaugh. RAC provided funding for Helen to fulfill this important commitment.
RAC presented a 5-day training course on environmental risk assessment to Nuclear Regulatory Commission (NRC) staff from April 27 through May 1, 2015, at the NRC Professional Development Center in Rockville, Maryland. John Till, Helen Grogan, Peter Shanahan, Art Rood, and Justin Mohler presented lectures during the week, and the course was very well received. The course was designed to allow participants to use the acquired knowledge for performance evaluations of licensee environmental assessments, performing environmental impact reviews, inspecting licensee programs, and managing environmental projects. RAC is contracted to present up to four more training courses for the NRC through 2019.
