Shielding and Bunker Design. Biomed J Sci & Tech Res 18(1)-2019. BJSTR. MS.ID.003106. ARTICLE INFO abstract The aim of this project was to develop a computerized algorithm that could be used to accurately assess the protection required (in terms of dose rates) in the design of Radiotherapy bunkers.

The main objective of a bunker used for external radiotherapy is to limit the radiation exposure of workers and public. When considering a radiotherapy bunker design, there are many parameters that should be taken into account as type of linear accelerator, intended techniques for treatment,

EGSnrc MC code was used to design a radiotherapy bunker with appropriate materials and thicknesses. A concrete density of 2.36 g/cm 3 was used as a shielding material for primary and secondary barriers. The lead slab was used in the entrance door.

Radiation therapy is typically administered through equipment known as Linear Accelerators (LINACs) which are installed in rooms commonly referred to as Bunkers due to the thick walls required for radiation shielding. Access to the bunker is typically via a twisted corridor known as “the Maze”, to contain the radiation.

The bunker walls, floor and roof are designed to prevent the passage of radioactive particles into adjacent external areas. Northrop works with the radiation consultant to provide a suitable structural solution.

effective dose from a linear accelerator (linac) to a point outside the radiotherapy bunker as low as reasonably achievable. Shielding design is particularly concerned with attenuation of the primary beam and secondary radiation in the form of head leakage, patient and wall scatter.

Sep 1, 2023 · We designed bunker shielding to keep radiation exposure limit 0.25mSv/year and occupational dose limit is 1 mSv/year.

Aug 1, 2018 · Most radiotherapy departments rely on various publications on the subject of bunker design such as [1], [2], [3], and use empirical formulae to estimate the protection required.
