| | THE CCLRC IONISING RADIATION SHIELDING POLICY (Site not responding. Last check: 2007-09-18) |
 | | Some of the projects initiated by CCLRC will require shielding to ensure that employees, visitors, trainees, contractors and members of the public near the perimeters of the CCLRC sites are not exposed to significant ionising radiation hazards. |
 | | Shielding is one of the most important protective features used to ensure radiation safety and this policy refers to the shielding design requirements for new projects, equipment and existing shielding that is to be modified. |
 | | In cases where the whole body exposure is not the limiting factor, the annual equivalent dose received by persons at CCLRC sites will be restricted to less than 5, 15 and 15 millisievert for the lens of the eye, skin and extremities respectively. |
