The four places on earth, Chernobyl, Fukushima, Hiroshima and Nagasaki with, likely, very high levels of radiation show no danger to mammals.
Below is a link to a Daily Mail article:

The idea that these nuclear contaminated areas are dangerous, clearly, needs further investigation. I'm not suggesting radiation doesn't have a half-life, just that you'd probably need to eat contaminated material for there to be a health issue. Clearly, if Chenobyl is contaminated and detrimental to life, then someone should have informed the vegetation and animals alike who seem to be thriving.
If you search YouTube for 'nuclear bomb hoax' you'll be presented with any number of 'conspiracy theorists', but we don't need to believe them, we just need to take another look at the evidence on the ground.
If any of this is true then we must conclude that Governments around the world are colluding to keep the general public scared and fearful. They know that a fearful person is more prone to propaganda and more willing to conform to their narrative.
Maybe it is time to 'let go of fear' and allow ourselves domain over our own perception. If we are not prepared to do this, someone or organisation will happily provide us with this service.
One of my favourite films for understanding consciousness and illustrating how to 'let go of fear' is by Director Guy Richie (who also co-wrote it) called 'Revolver' 2005.
