Workers were grouped into three categories. Flag 1: Workers with no monitoring or zero doses. Flag 2: Workers with recorded cumulative neutron doses not exceeding 10% of the total equivalent dose for external radiation. Flag 3: Workers with recorded cumulative neutron doses exceeding 10% of the total equivalent dose for external radiation.

Workers were grouped into two categories. Flag 1: Workers with no deposition. Flag 2: Workers with known (France, UK and U.S.) or suspected (UK) deposition.
