Illustration of the phantom used to simulate the operator’s head where TLDs were positioned at different depths in five slices (a, b, c, d and e). For the head protector and ceiling mounted lead shield studies all TLD positions (light grey and dark grey) were used, while for the extended thyroid protector study the TLD positions 1–14 (dark grey) were used. On the right, slice c is shown enlarged, illustrating the numbering in each individual section
