Abstract
To improve radiotherapy services, Dr. Kariadi hospital Semarang plans to install a new Brakhiterapi machine using Co-60 sources. The radiotherapy room that was built was previously used for Brachytherapy using the Ir-192 source. In accordance with nuclear regulations in force in Indonesia, the Co-60 brachytherapy machine must be installed in a radiotherapy room that has obtained a new construction permit from the Nuclear Energy Supervisory Agency (Bapeten), considering that the radioactive source to be used is different from the previous radioactive source, activity and energy. The calculation document for radiation retaining wall thickness is compiled as one of the requirements to obtain construction approval from the Nuclear Energy Supervisory Agency.
