Radiation Physics Division Groups

Dosimetry Group

The Dosimetry Group advances the measurement of quantities important in the radiological sciences through programs in the dosimetry of x-rays, gamma-rays, electrons, and other charged particles.

The Neutron Physics group maintains and supports the nation's premier fundamental neutron physics user facilities. The group has developed the nation's only high-resolution neutron imaging user facility (NIF) for fuel cell research. We maintain, and disseminate measurement standards through both

Radioactivity Group

The Radioactivity Group's mission is to develop, maintain, and disseminate radioactivity standards, develop and apply radioactivity measurement techniques, and engage in research to meet the requirements for new standards.
