Explanation:
about 78 % of the air is nitrogen and 21% is oxygen . These two gases can be seperated by fractional distillated of liquid air . Air is filtered to remove dust ,and then cooled in states until it reaches -200'C at this tempereture it is liquid . The air has been liquefied. And after a distillation process you can obtain nitrogen from a mixture of nitrogen and oxygen .
For the answer to the question above, one of the most important risks to take into account regarding the mining of uranium is the possibility of nuclear decay taking place and contaminating the worker. So I believe the answer is the last one which is <span>the health hazards that are associated with uranium mining</span>
