Materials and Methods: In this research, absorbed dose to skin and depth dose from the skin surface have been calculated for 90Sr/90Y, 147Pm, 32P beta emitter radioisotopes by using input parameters: activity of source, cover thickness, cover density, air gap thickness, radiation time and different source geometries. Results: Absorbed dose variation was calculated for beta sources in different source forms, namely, point, 2-D disk, cylindrical, spherical and slab sources. The results show that a cylindrical source causes the minimum damage to skin cells. Therefore, this shape of source is the best with respect to radiation protection. Discussion and conclusion: The VARSKIN2 code is a very useful tool for skin dosimetry, as well being fast, accurate and user friendly. It can be used for dose optimization calculations especially for beta sources over human skin.  }, keywords = {Beta sources,Radioactive Contamination on Skin,Absorbed Dose,VARSKIN2 Code}, url = {https://ijmp.mums.ac.ir/article_7289.html}, eprint = {https://ijmp.mums.ac.ir/article_7289_ef82f5158afe8abd9cc804b639676ae5.pdf} }
