Schematic illustration of the shielding effect, RSE, where green indicates RSE > 0.5; yellow RSE > 0.2–0.5; orange RSE > 0.1–0.2; and red RSE ≤ 0.1. The following set-ups were used A no head-protection; B the head protector; C the prototype standard thyroid collar; D the extended thyroid protector; E ceiling mounted lead glass shield; and F a predicted result from a combination of the head protector and the extended thyroid protector. The shielding-effect ratio for the unshielded set-up A the ratio is: RSE = 1-[Hp(0.07)unshielded/Hp(0.07)unshielded)]. To see the RSE at depth look at respective slice a-e with the coloured measure-positions in each figure A-E
