When solar radiation hits the earth's atmosphere some of it is reflected out, but most enters, warming our planet and making it hospitable to life. The earth in turn emits infra-red radiation, thus cooling itself. Some of this infra-red radiation is trapped by 'greenhouse gases' including water vapour, which act as a sort of blanket, or heat trap. This threat to life on Earth is serious. Warped idea of science and development.
Background radiation exists everywhere on earth.
By altering cells their ability to 'rest' is destroyed, thus causing uncontrolled multiplication - cancer. Nothing, absolutely nothing can justify such risks to humanity from the malignant nuclear ambitions of a powerful few. Wastes will remain toxic for anywhere between 25,000 and 250,000 years. What is worse, we may not even be able to communicate to future generations that a particular site is toxic. Besides, no one event talks of the risks to society if such sites become the focus of terrorist attack, a very likely possibility given the increasing violence in human hearts.
