Type B uncertainty … input Source geometry

➢ Besides verified, the uncertainty in construction details (tolerances) must be included in the uncertainty budget. In example: uncertainty map for an I-125 seed

IsoSeed I25.S17plus:

MC dose rate distr.

% uncert.: geo. + type A

% uncert.: geo. + type A + cross secs.
