Health Physics Society President Emeritus Nolan Hertel has been selected as the 2025 recipient of the Randall S. Caswell Award for Distinguished Achievements in the Field of Ionizing Radiation Measurements and Standards by the Council on Ionizing Radiation Measurements and Standards (CIRMS).

The CIRMS stated in its letter to Hertel:

Your contributions to radiation protection and measurement science have been truly remarkable. As a pioneer in neutron dosimetry and radiation shielding, you have shaped international standards through your leadership on key committees, including the ANSI/ANS 6.1.1 working group on fluence-to-dose conversion coefficients and the development of ICRU Report 95, which established operational quantities for external radiation exposure.

Your tenure as CIRMS President advanced national measurement standards, while your three decades at Georgia Institute of Technology and work at Oak Ridge National Laboratory have left an indelible mark on our field.

CIRMS went on to say that Hertel's dedication while supervising over 80 graduate student PhD dissertations and MS theses and his innovations in detector materials and radiation detection instruments "exemplifies the kind of impactful leadership that the Caswell Award celebrates."

The Randall S. Caswell Award will be presented on 9 April 2025 at the CIRMS annual meeting, where Hertel will give the Caswell Award lecture. More information about the award can be found on the CIRMS website.
