The use of beta radiation in treating superficial skin tumors can be advantageous, especially when there is a bone or cartilage located right beneath the tumor. The few-millimeter range of this radiation in tissue may enhance the protection of the sensitive structure around the tumor when the treatment is delivered. However, besides its advantages, this short range of beta radiation has its own disadvantages when it comes to practical dosimetry. Therefore, simulation and calculation methods are used when experimental dosimetry is challenging or unfeasible. MC simulation is a powerful technique that offers enormous flexibility in simulating the study setup, making it the method of choice in nonexperimental dosimetry. However, they can be computationally heavy techniques. Analytical methods are another set of techniques for dosimetry of beta radiation that can produce results faster than MC methods, although they are less favored because of the lower accuracy. In the current attempt, we used MC simulation and analytical calculation for dosimetry of radiation dose from a multiwell skin brachytherapy applicator with two beta sources. Results of the two approaches were compared to see how accurate the analytical method is.
