ANS continues to expand its certificate offerings
It’s almost been a full year since the American Nuclear Society held its inaugural section of Nuclear 101, a comprehensive certificate course on the basics of the nuclear field. Offered at the 2024 ANS Winter Conference and Expo, that first sold-out course marked a massive milestone in the Society’s expanding work in professional development and certification.

The external bremsstrahlung (EB) spectra generated in thick targets by the beta particles of 170Tm are measured using a 4.55- × 5.08-cm NaI(Tl) crystal detector in a good geometry setup. The raw spectra are unfolded using the Liden-Starfelt procedure. The unfolded EB spectra are compared with Bethe-Heitler, Elwert-corrected Bethe-Heitler, Morgan-corrected Bethe-Heitler, and Tseng and Pratt theories. The experimental spectra are found to agree with the theory of Tseng and Pratt up to a certain energy and deviate positively thereafter. The deviation from theory increases with increasing energy and atomic number of the target material.
