In 1980 the Internal Emitters Committee of EULEP organised a symposium in Rotterdam on Bone and Bone Seeking Radionu cI ides: Their Physiology, Dosimetry and Effects. The speakers for this meeting, mostly from EULEP associ ated laboratories, were chosen to review this field of scientific research mostly for the benefit of interested scientists who were not actively researching with bone seeking radionuclides. This meeting was a success and its proceedings were subsequently published in the form of a book by the Commission of the European Communities, reflecting the great importance that both EULEP and the Radiologi cal Protection Programme of the Commission of the European Communities attaches to the study of radionuclides that deposit in bone. The Metals in Bone symposium in Angers was intended to serve a different function from that of the meeting held in Rotterdam in that, while these proceed ings will certainly be of interest to non-involved scientists, the meeting was intended to be of most benefit to those actively researching the metabolism and effects of bone-seeking metals. Moreover, in an attempt to increase the value of its discussions and the number of interested and participating scientists, the remit of the meeting was broader and set to include papers on stable as well as radioactive metals."
