high energy photons - calibration

[mirolies@nbnet.nb.ca (Miroslav Lieskovsk\})]

Hallo RADSAFE:

Please, help me to identify any institution or organization that would either:

1a) perform a fluence/flux density calibration for high energy photons,
especiacially, of those from N-16 (6.13 MeV and 7.12 MeV).
1b) perform a dose/dose rate calibration for the same as above at the
radiation protection levels. 

These are of concern in the power reactor environment.

2) distribute an Am-241 or Pu-239(alpha,n)C-13 source with prompt N-16
gammas.  Preferably, having the source traceable to the NIST or the like
institution.    

3) perform some of the 1a,b) on bremstrahlung photons from betatrons or linacs.

Thank you very much.

Sincerely,
