Nuclear Technology —— Good or Bad?

These days many people are afraid of nuclear technology because of the dangers or threat associated with its usesuch as nuclear explosion and nuclear weapons. The most worrying aspect of nuclear technology, however, is its use for military purposes. Enough atomic bombs have already been created to completely destroy the planet.

Although it is true that nuclear weapons pose the greatest threat to human life, the use of nuclear technology for peaceful purposes also carries some positive meanings. Nuclear power stations provide an important source of cheap power for many industrialized nations and some developing countries. In addition, nuclear radiation treatment can be used in medical science.                                                                                                                                       
    In my opinion, nuclear technology certainly has positive uses and is nonetheless dangerous, and it would have been better if it had never been used to create nuclear weapons. If life on Earth is to continue, all the nuclear nations of the world should agree to disarm and reconsider nuclear safety as soon as possible.
