Assessment of the uncertainty in 50 Hz foetal exposure due to tissues conductivity variation

In this paper, the influence of conductivity values applied to the foetal tissues at 3, 7 and 9 months gestational age on the electric field distribution induced by a 50 Hz uniform magnetic field was explored by means of stochastic dosimetry performed by making use of polynomial chaos theory. The maximum variations of induced electric field peak can reach up to 12 % in foetal fat.
