Nuclear Tractors: Mutating Wheat

The Soviets embarked on Project Gamma Kolos, also known as nuclear tractors, in an attempt to induce mutations in wheat seeds before planting them. These tractors were equipped with containers of cesium 137 and lead shielding to protect the driver. The irradiation of wheat seeds aimed to generate beneficial mutations in the crops. Additionally, radiation was applied to the harvested grain to prevent germination.
