摘要：

Methodologies for the design of facilities dedicated to radiotherapy equipment are available in the literature, in which physical parameters of a very limited number of shielding materials are also offered. In this paper, a non-standard methodology is proposed for the evaluation and redesign of rooms used for superficial radiation therapy with energies of up to 100 kV, based on the calculation methodologies of relevant documents such as IAEA SRS No. 47 and the IPEM Report 75, in which the physical parameters of the materials are evaluated from the NIST data. The methodology was applied to the redesign of a room for the installation of a SENSUS SRT-100 equipment. Significant differences were found compared to conventional methodologies, especially for barriers that are insufficiently armored and that are very close to the source. For the rest of the barriers, the results show that there are no differences in the use of one or another methodology.
