Activity limits are given in the ADR table 188.8.131.52.2.1 p. 224 for up to 382 nuclides.
For nuclides not mentioned in this table (so called unknown nuclides) activity limits are given in table 184.108.40.206.2.2 p. 242. The given limits depend on the type of radiation emitted by the nuclide which can be a beta or gamma emitter, an alpha emitter (if more than 1 alpha per 1000 decays is emitted but no neutrons) or a neutron emitter. In Nucleonica the emitter type of each nuclide is determined and indicated in the eShip data grid as well as in the report e.g. β/γ.
If the activity limits are given in table 220.127.116.11.1, the emitter category is not relevant - this is then indicated by the value in parenthesis e.g. (β/γ).
