Claim:
1. A gamma ray spectroscopy monitoring system comprising: (i) at least one sample cell located inside a hot cell that is connected to a medical isotope reactor; (ii) at least one measuring port located in and through the hot cell and/or a hot cell wall, the measuring port forming at least one gamma ray window through the hot cell and/or a hot cell wall, where the measuring port has an inner gamma ray transparent plug located at the internal end thereof and an outer gamma ray transparent plug located at the external end thereof, wherein the inner and outer gamma ray transparent plugs serve to prevent the transport of volatile radioactive material out of the hot cell through the at least one measuring port; (iii) at least one adjustable collimator device operably coupled to the at least one measuring port; (iv) at least one shutter located outside of the hot cell and operatively coupled to the outer end of the measuring port; and (v) at least one high resolution gamma ray spectrometer operably coupled to the hot cell and positioned in such a manner that gamma rays from the hot cell are supplied to the at least one high resolution gamma ray spectrometer through at least one opening in the shutter that is transparent to gamma rays.
