News from the Library: Facilitating access to a program for radiation shielding - the Library can help

MicroShield® is a comprehensive photon/gamma ray shielding and dose assessment programme. It is widely used for designing shields, estimating source strength from radiation measurements, minimising exposure to people, and teaching shielding principles.


Integrated tools allow the graphing of results, material and source file creation, source inference with decay (dose-to-Bq calculations accounting for decay and daughter buildup), the projection of exposure rate versus time as a result of decay, access to material and nuclide data, and decay heat calculations.

The latest version is able to export results using Microsoft Office (formatted and colour-coded for readability). Sixteen geometries accommodate offset dose points and as many as ten standard shields plus source self-shielding and cylinder cladding are available. The library data (radionuclides, attenuation, build-up and dose conversion) reflect standard data from ICRP 38 and 107* as well as ANSI/ANS standards and RSICC publications. Custom materials are based on ANSI/ANS-6.4.2-2006. Exposure dose and fluence rates and the ICRP 51 and ICRP 74 results can be customized on the dose-equivalent report.

The CERN Radiation Protection Group is intending to buy the software. In order to facilitate this operation, the Library wishes to gather expressions of interest in this product. Please contact us.

*ICRP Publication 107 (Nuclear Decay Data for Dosimetric Calculations, Annals of ICRP Volume 38, No. 3, 2008) provides an updated nuclear library containing 1252 radionuclides of 97 elements. ICRP Publication 107 supersedes ICRP Publication 38 (1983) and both libraries along with the original Grove Library are provided with the software.
