This page will be a resource for the development of dosimetry standards for radiobiology. The program will be launched through an upcoming workshop. The upcoming NIAID/NCI/NIST-sponsored workshop on Radiation Dosimetry Standardization for Radiobiology is to be held September 15 – 16, 2011. The meeting has two goals and your participation is of key importance in achieving both. The first is immediate and is to highlight the importance and necessity of dosimetry standardization in radiation research, whether it involves in vitro or in vivo approaches, or large or small animal models. Most of the presentations will be aimed at reaching this goal. The other, and equally important, objective is long term. It will be addressed in an open forum discussion focused on the future of radiation dosimetry standardization, including a formal system for coordinating standardization efforts as well as the establishment of a continuing education series through national conference tutorials, publications, and web-based resources.
