Abstract:
Radiations and particles have many application in several fields of human activities. In addition to their confirmed application to fundamental research they are in fact widely applied in all fields of science, medicine, chemistry, material science and so on. Up to today radiations have been produced by radiation sources (conventional accelerators, X-ray tube, radioactive sources, etc.) with the well-known connected problems of costs, parameters and safety.
Since few years, following the development of lasers able to focus ultra-short high intensity pulses onto targets, became possible the generation and acceleration of charged particles, opening new perspectives namely in high energy beam facilities.
From than on all practices concerning the use of laser in relativistic and ultra relativistic regime have been regarded as practices with radiation risk and consequently treated.
The aim of this presentation is to focus some radiological protection aspects, that a project manager should take into account in designing a facility for lasers from hundreds terawatt to hundred petawatt peak power,focusing mainly
licensing requirements,
prompt and residual radiation fields,
shielding of radiations produced,
shielding materials,
radiation monitoring,
determination of any environmental impact
and other specific operational requirements of an “accelerator facility
About the speaker:
Adolfo Esposito, after his degree in physics in 1976 obtained at the “Sapienza” University in Rome with the highest grades, he joined the LNF radiation protection group, where is still work as Radiation Protection Expert.
He is involved from 1981 to today in
