My edition ?? [circa 1960] goes up to 100 GeV. But the modern way is to use XCOM http://www.nist.gov/pml/data/xcom/ to get the photon cross-sections.
If you are doing doserate calculations, then the buildup factors will be the tough part. frazier Frazier Bronson CHP Scientific Director Canberra 800 Research Parkway Meriden CT 06450 USA Tel: +1-203-639-2345 From: McCarthy, John:(GenCo-Nuc) [mailto:[email protected]] Sent: Tuesday, December 15, 2015 1:51 PM To: [email protected]; Holmes, Stephen J:(GenCo-Nuc); Cady, Jeffrey James:(GenCo-Nuc) Subject: [powernet] Transmission 16N photons in various materials Can anyone provide a good reference for transmission of 16N photons through lead and steel?

This is based on the paper by Luetzelschwab et. al, Health Physics, October 2000. We have enough activity at our Oconee Nuclear Station to make a direct measurement but haven’t managed to find the time to do it. You may use me as the contact. My information is on the line below.
