RADIATION EXPOSURE IN MÖSSBAUER SPECTROSCOPY

This paper deals with the risks involved in routine operations as well as in potentially hazardous management of radioactive sources in a typical Mössbauer spectroscopy research laboratory. It comes from a direct experience at the University of Parma, Italy, and from information obtained from more than 50 different Mössbauer laboratories all over the world. A review of the normal procedures performed by researchers and technicians in the Mössbauer laboratory is presented along with the relative dose evaluations. Radiation doses have been calculated and measured from various situations, ranging from daily operations and maintenance work to radiation risks in case of incorrect procedures and/or device failures.
