Soon after the Chernobyl disaster, the Soviet Union tried to cover up the severity of Chernobyl to try and prevent panic by not tellling other countries and news stations. Due to lack of diplomacy about the disaster, more people were endangered as radiation spread through the Ukraine and countries as far away as Sweden, and people were getting radiation poisoning. Due to this, people started to vomit their lungs and liver, get rashes all over their skin, and feel very weak and sluggish.

People started to die or get very badly injured and because of this, people started to realize how serious Chernobyl was and began protesting to end nuclear energy once and for all. These riots and protests attracted government attention and through global diplomacy, the International Atomic Energy Association made nuclear energy safer than it ever was before.
