The Goddess of Bliss and its plutonium

In the 60s the Himalaya was still considered the Shangri-La of exploration, a wild and legendary place free from celebrity that would have characterized it thanks to the mountaineering of the late twentieth century. The story I am about to tell concerns the 24th highest mountain in the world, the Nanda Devi (7,816m), which is located in India in the Great Himalaya in the northern sector of Uttar Pradesh in the domain of the Kumaum region, one of the areas with highest population density in the world.
