Radiation Protection for Medical Research Laboratories in the General Hospital of Vienna (University Hospital)

In the floors six, seven and eight of the general hospital of Vienna over eighty research laboratories for medical investigations with open and closed radioactive sources are installed. In these laboroatories different working places and digestors for the handling of open radioactive materials in gaseous, liquid and aerosol form are placed for medical research purposes. These laboratories are divided dure to the manner of handling and the amount of activity in three categories. The laboratories themselves and the different types of digestors are mantled and shielded with lead of variable thickness. For all these categories of working places and digestors the radionuclides were listed and the highest amount of these different radionuclides were calculated and tabulated in a form sheet, which is the basis for working procedures in these laboratories. Also the paper shows all radiation protection measures and the results of the dose- and dose rate measurments and the various inspection tests. At least the licensing procedures for radiation protection in detail will be shown and the important features listed.
