2015年6月1日 · The National Council on Radiation Protection and Measurements (NCRP) announces the publication of NCRP Report No. 147, Structural Shielding Design for Medical X-Ray Imaging Facilities. The Report presents recommendations and technical information related to the design and installation of structural shielding for facilities that use x rays for ...

NCRP Report No. 49 that address structural shielding design for megavoltage radiotherapy facilities using x and gamma rays. This Report was prepared through a joint effort of NCRP

Report No. 147 (2004) presents recommendations and technical information related to the design and installation of structural shielding for facilities that use x rays for medical imaging. The purpose of structural shielding is to limit radiation exposure …

NCRP‐147 •NCRP 147 supersedes NCRP 49 (1976) and discusses the various factors to be considered in the selection of appropriate shielding materials and the calculation of barrier thicknesses. •Uses Effective Dose (E) as the limiting radiation protection quantity, but sets

NCRP Report No. 147 was our take on “best practice” at one moment in time... But we hope that our methods will be rigorous enough to last a few years! Ben Archer, Linc Hubbard, Bob Dixon & I meet at Bob’s beach house (off season... Can you tell the Yankees from the Southerners?) *Of shielding design, that is!

The Report presents the fundamentals of radiation shielding, discusses shielding design goals for controlled and uncontrolled areas in or near x-ray imaging facilities, and defines the relationship of these goals to the NCRP effective dose limits for radiation workers and members of the public.

Uncontrolled areas occupied by individuals such as patients, visitors to the facility, and employees who do not work routinely with or around radiation sources. Areas adjacent to, but not part of, the x-ray facility are also uncontrolled areas. Accepted radiation level in the occupied area.
