Nguyen 1 – radioactivity harder to transfer than you think

Many people believe objects exposed to radioactivity become radioactive; objects exposed to radioactivity have radioactive isotope dust sticking to them and can be easily cleaned by washing the objects with water. Most high radioactive waste stays in the reactor. To cause reactor material to spill out, all three systems in reactor must be broken at the same time. There are also coupons outside the reactors which are removable and used to analyze the reactor every 5 years. There are 3 barriers between radioactivity and the environment: the cooling rods, fuels tank, and walls of the dome, all of which are hard to penetrate. In case the system overheats, the control rods can be lowered into the reactor pool. Once the control rods touch the reactor pool, the graphite absorbs the neutrons, the system automatically shuts down, and the reaction stops. Read the full essay
