Support for the "Vancouver call for action to strengthen expertise in radiological protection worldwide": the position of organisations in formal relations with the International Commission on Radiological Protection (ICRP).

The International Commission on Radiological Protection (ICRP), recently expressed concern that "a shortage of investment in training, education, research, and infrastructure seen in many sectors and countries may compromise society's ability to properly manage radiation risks" and in 2022 announced the "Vancouver call for action to strengthen expertise in radiological protection worldwide". As representatives of organisations in formal relations with ICRP, we decided to promote this position paper to declare and emphasise that strengthening the expertise in radiological protection is a collective priority for all of us.

Whole body effective dose equivalent dataset for MAX and FAX shielded with Common Aerospace Materials in deep space.

Materials have a primary purpose in the design of space vehicles, such as fuels, walls, racks, windows, etc. Additionally, each will also affect space radiation protection. Using the On-Line Tool for the Assessment of Radiation in Space (OLTARIS), version 3.5, analysis package, this article includes the whole body effective dose equivalent (ED) data from human phantoms being shielded by 59 aerospace materials for deep space travel. To represent the average anatomy of an astronaut, the Female Adult voXel (FAX), 2005 version, and the Male Adult voXel (MAX), 2005 version, human phantoms are used. A simple spherical geometry, which is composed of a spherical shell with the human phantom placed in the center, is also used. Eighteen shielding thicknesses ranging from 0.01 to 1000 g per centimetres squared are evaluated and the ray distribution used in this study is the 1002 geodesic. All aerospace materials are categorized into four groups: metals, polymers, composites, and fuels, hydrides, and liquid gases. These materials include common fuels and propellants used in space travel, engineered materials developed to significantly increase the absorption of secondary radiation, and materials in the early stages of development for the purpose of meeting both shielding and structural needs of future spacecraft missions. The data in this article is used for the paper, "Evaluating the Effectiveness of Common Aerospace Materials at Lowering the Whole Body Effective Dose Equivalent in Deep Space," [13].

Panel session on "safety, health and the environment: implications of nuclear power growth".

This paper summarizes the presentations and the insights offered by panelists John P. Winston, Robert Bernero, and Stephen LaMontagne during the Panel on Safety, Health and the Environment: Implications of Nuclear Power Growth that took place during the NCRP 2009 Annual Meeting. The paper describes the opportunities and the challenges faced in the areas of infrastructure development, radiation control, licensing and regulatory issues, and non-proliferation as a consequence of the forecasted growth in nuclear power capacity worldwide.
