Abstract
The maximum credible accident is the most serious accident which one can conceive without involving any physical impossibility within the frame of hypotheses which have a probability of occurence considered as not negligible.
In the case of the laboratories for production of radioisotopes this accident is defined as a fire which would destroy either part of the laboratories.
The quantities of radioisotopes to be supposed in the laboratories when the fire starts are the maximum forseeable quantities with respect to the existing installations.
The doses by direct radiation from the radioactive cloud, the inhalation doses and the surface depositions have been calculated for the different dangerous isotopes and compared to the corresponding guide-levels; it appears from this comparison that a fire in the gamma laboratory could result in a rather slight problem of iodine inhalation and deposition.
