You can select a radioisotope from the left panel to display all its emissions.

OpenDose is currently using radioisotope decay data from the ICRP publication 107 [1] for S values calculation. It provides electronic data for 1252 radioisotopes (of 97 elements), containing information on their half-lives, decay chains, and yields - energies of radiations emitted by their nuclear transformations.

This section allows to display the emissions of these 1252 radioisotopes. An interactive chart shows the yield (Bq-1.s-1) and energy (J) of their radiation types:
