Shielding Design for Linear Accelerators Using NCRP Report on Vimeo
NCRP makes several conservative assumptions designed to produce safe vault designs at reasonable cost. The following are examples of conservative assumptions. Neglects patient attenuation (30%) Assumes beam takes the shortest path through the barrier. (i.e. That the beam is incident normal to the plane of the barrier). Overview & Basis of Design for NCRP Report Structural Shielding Design and Evaluation for Megavoltage x- and Gamma-ray Radiotherapy Facilities Raymond K. Wu, PhD OhioHealth Hospitals Columbus, OH This Report was prepared through a joint effort of NCRP Scientific Committee on Design of Facilities for Medical Radiation. ncrp PDF download.1 Overview & Basis of Design for NCRP Report Structural Shielding Design and Evaluation for Megavoltage x- and Gamma-ray Radiotherapy Facilities.

Actual facility designs will be used as the example calculations of required shielding for Linear Accelerators to be installed in modern radiation therapy facilities. Examples of methods to minimize the amount of additional shielding needed for new departments due to well planned designs will be given.
As the equipment in radiation oncology departments has evolved to linear accelerators with IMRT as state of the art modalities, the requirements for adequate radiation shielding for these modalities has become more rigorous. Architectural designs no longer depend on standard maze design rectangular rooms. Innovative layouts and utilization of multiple layers of shielding materials allow much greater flexibility in room designs. Shielding calculations for these challenging designs will be covered in this presentation.
Educational Objectives: 1. Understand the workload and occupancy factors to be used for dual energy linear accelerators with IMRT capabilities to determine required structural shielding to meet exposure limits for occupational personnel and the public. Understand the effectiveness of existing and additional structural shielding materials to provide radiation protection and methods to calculate the required amounts of these materials.
Understand the calculation methods to be used in performing the shielding calculations for all aspects of linear accelerator installations to insure adequate shielding is provided to meet applicable state ncrp 151 pdf download ALARA requirements.

NCRP Report Structural shielding design and evaluation for megavoltage x-and gamma-ray radiotherapy facilities National Council on Radiation Protection and measurements () $ This report, which supersedes NCRP Report 49 for megavoltage x-and gamma-ray radiotherapy facilities, is an essential requirement for anyone. The purpose of radiation shielding is to limit radiation exposures to members of the public and employees to an acceptable level. This Report presents recommendations and technical information related to the design and installation of structural shielding for megavoltage x- and gamma-ray radiotherap. Shielding Design for Linear Accelerators Using NCRP Report from Shielding Design for Linear Accelerators Using NCRP Report The application of the structural shielding design techniques and goals as outlined in NCRP Report Structural Shielding Design for Medical X-ray Imaging Facilities (November ) and NCRP Report
