description Two new contact circumstances called ‘stand-lie’ and ‘front–rear’ are implemented to the merged phantom tool. To allow more flexibility for users when they calculate the dose for a volume of interest (VOI) with arbitrary geometry, an optional utility to convert segmented structure information from the CARIMAS software into parallel geometry of GEANT4 is provided. The effective dose for a person who has been in contact with a male patient being treated for thyroid cancer with 131I is calculated for four circumstances: opposite, side by side, stand-lie and front–rear. The biggest dose is the ‘opposite’ circumstance and the smallest one is the ‘stand-lie’ circumstance. Using the dose distribution in the patient’s body and applying the right circumstance should be done to optimise the dose calculation for the contact person.
