Evaluation of the penetration depth and dose distribution of single energy electrons in the neck phantom using MCNPX code

Penetration and estimation of absorbed dose of electron in soft tissue is investigated in this paper. Neck phantom was simulated by MCNPX code version 2.6. The Phantom was included skin, adipose, neck tissue, neck bone and thyroid glands. Radiation source kept near to the skin surface and located in the back of the neck. Electrons were collided perpendicular to the skin surface. The curves show that by increasing the electron energy, the electron penetrate more in tissue and peak of electron stopping power curves appear in higher depth.
