Radiological protection evaluation of four newly built X-ray diagnostic apparatus at a hospital

In accordance with the requirements of relevant national standards, a project of four diagnostic medical apparatus at a hospital was evaluated for acceptance, with respect to environmental protection monitoring and the radiological protection effect in the workplace. Based on dose data of measurement points, the annual doses for radiation staff and public are calculated to be 1.8 mSv/a and 0.0048 mSv/a, respectively, which are both lower than the relevant constraint values. It turns out that the project is compliance with national standards, concerning the radiation level and machine room radiation protection devices, and the conditions of completion acceptance are met.
