There have been significant developments for molecular imaging and targeted radionuclude therapy using radioisotopes. This contrasts a decreasing need for use of radioisopes for in vitro experimental purposes because of alternative non-radioactive labeling methods, which in tern leads to a decreasing availability of the facility for education and training as to how to handle radioisotopes.
