The Janus Experiments investigated the effects of exposure to neutron radiation and gamma radiation on mice and dogs. They consisted of ten large scale experiments conducted at Argonne National Laboratory from 1972 to 1989. To explore various relationships, the studies varied radiation type, dose rates, total dose and fractionation.
