    Nuclear reactors fuelled with uranium can be used to produce artificial radioactive substances called radioisotopes for use in industry scientific research and medicine Alternatively many of these radioisotopes can be produced in special machines called accelerators which do not require the use of uraniumFly ash is commonly used as an additive to concrete building products but the radioactivity of typical fly ash is not significantly different from that of more conventional concrete additives or other build ing materials such as granite or red brick

  • Health Dangers of Uranium Mining by Gordon Edwards PhD June 11 5 Non Penetrating Alpha Radiation Slide 49 The most damaging atomic radiation is a non penetrating type called alpha radiation Alpha radiation is often difficult to detect with radiation monitors because it has a very short path and little penetrating powerAnswers to questions about Mosaic in Florida including phosphate mining land reclamation public health risk water use and quality water consumption radiation risk radon gas gypstack gypsum stack phosphogypsum gyp stacks

  • Uranium in the environment refers to the science of the sources environmental behaviour and effects of uranium on humans and other animals The radiation hazards of uranium mining and milling were not appreciated in the early years resulting in workers exposed to high levels of radiationIf however there is a need to use a public road railway or waterway the requirements of the Code must be complied with 2 Managing naturally occurring radioactive material NORM in mining and mineral processing

  • Results The radioactive impact of uranium mining and milling was illustrated through case studi Environmental radioactivity monitoring and surveillance carried out in areas impacted by uranium mining and milling industry showed generally that dose limit for members of the public was exceededImpacts of naturally occurring radioactive material standards on mining and minerals processing For mining and minerals processing radioactivity and radioactive materials are always present and appropriate management and regulation that is commensurate with the actual risk is important ARPANSA regulates federal entities that use
