The Structural Shielding of the New Radiotherapy Bunker at the General Hospital of Yaounde in Cameroon
Journal of medical physics and applied sciences is an international peer reviwed journal aiming to publish the most relevant and recent research works across the world. Medical Physicists will contribute to maintaining and improving the quality, safety and cost-effectiveness of healthcare services through patient-oriented activities requiring expert action, involvement or advice regarding the specification, selection, acceptance testing, commissioning, quality assurance/control and optimised clinical use of medical devices and regarding patient risks and protection from associated physical agents (e.g. x-rays, electromagnetic fields, laser light, radionuclides) including the prevention of unintended or accidental exposures; all activities will be based on current best evidence or own scientific research when the available evidence is not sufficient. Medical physics is also called biomedical physics, medical biophysics or applied physics in medicine is, generally speaking, the application of physics concepts, theories and methods to medicine or healthcare.
We are sharing one of the most cited article from our journal. Article entitled “The Structural Shielding of the New Radiotherapy Bunker at the General Hospital of Yaounde in Cameroon: An Enhancement of Radiation Protection” was well written by Dr. Tetchoka Manemo Cedric.
The purpose of the this work is the assessment of the new radiotherapy bunker and structural shielding to better enhance radioprotection and reducing the rate of mortality of cancer patients at the General Hospital of Yaoundé (GHY) Cameroon. We used data from the Cobalt-60 machine (60Co), Linear Accelerator (LINAC) and measurements done on the new radiotherapy bunker. From our results and analyses, with the Tenth Value Layer (TVL) for 90° scattered radiation, doors with 6.5 mm thickness of lead would reduce the weekly dose as follows: From 490 μSv·week–1 to around 49 μSv·week–1 case of 60Co; From 435 μSv·week–1 to around 43 μSv·week–1 case of 6 MeV Linac; From 289 μSv·week–1 to around 28 μSv·week–1 case of 18 MeV Linac, which are well within the design dose limit (120 μSv·week–1, 6 mSv/a) very acceptable.
