II) Summary,
In the debate on the safety of nuclear power there are genuine
anxieties we have to deal with,First,there is no evidence that
the long term effects of the low level of radiation causes higher
occurrence of cancer or other diseases than the national average
and the radiation from nuclear power is much weaker than that
from other sources,Second,chances of a "run away" leading to
an atomic explosion are slim,Finally,radioactive waste can be
separated in a chemical way,disposed of or stored in stainless
steel double-walled tanks or converted to a solid,So the
advantages of nuclear power outweigh the risks and nuclear
energy is the alternative we can rely on to fill the energy gap,

that the incidence of cancer or other diseases among the workforce of
nuclear plants is higher than the national average,and nuclear
radiation from nuclear power is much weaker than that from other
sources,Second,chances of a "run-away" that lead to an atomic

anxieties we have to deal with,First,there is no evidence that
the long term effects of the low level of radiation causes higher
occurrence of cancer or other diseases than the national average
and the radiation from nuclear power is much weaker than that
from other sources,Second,chances of a "run away" leading to
an atomic explosion are slim,Finally,radioactive waste can be
separated in a chemical way,disposed of or stored in stainless
steel double-walled tanks or converted to a solid,So the
advantages of nuclear power outweigh the risks and nuclear
energy is the alternative we can rely on to fill the energy gap,
