ASSESSMENT OF THE RADIOLOGICAL IMPACT OF THE 50 GeV BPS1) ON ITS ENVIRONMENT

  • The site proposed for the construction of the 50 GeV Proton Synchrotron of theAcademia Sinica near Beijing is close to residential areas and places with a high cul-tural and touristic value. The impact of the construction and operation of the accele-rator on the environment and in particular the radiological impact is of Prime concernto the authorities who licence and support the project. It is shown in the present re-port that the influence on the area outside the fence of the proposed site is indeedvery small: the stray radiation level can be kept below 20 mrem/y outside the fence,and the radioactivity released in air will not, in the most exposed location outsidethe accelerator area, give rise to a submersion does of more than 10mrem/y. Provid-ed some precautions are taken. The release of activity by water will not result inactivity concentrations of more than one tenth of the maximum permissible concentra-tions according to the legislation of the People' s Republic of China. The estimationsin this report have been based both on calculations and on experience with the CERNand other accelerators. The conclusions arrived at confirm that the radiological im-pact on the environment of high-energy accelerators of such beam powers(~20 kW)are insignificant.

Abstract: The site proposed for the construction of the 50 GeV Proton Synchrotron of theAcademia Sinica near Beijing is close to residential areas and places with a high cul-tural and touristic value. The impact of the construction and operation of the accele-rator on the environment and in particular the radiological impact is of Prime concernto the authorities who licence and support the project. It is shown in the present re-port that the influence on the area outside the fence of the proposed site is indeedvery small: the stray radiation level can be kept below 20 mrem/y outside the fence,and the radioactivity released in air will not, in the most exposed location outsidethe accelerator area, give rise to a submersion does of more than 10mrem/y. Provid-ed some precautions are taken. The release of activity by water will not result inactivity concentrations of more than one tenth of the maximum permissible concentra-tions according to the legislation of the People' s Republic of China. The estimationsin this report have been based both on calculations and on experience with the CERNand other accelerators. The conclusions arrived at confirm that the radiological im-pact on the environment of high-energy accelerators of such beam powers(~20 kW)are insignificant.
