s tota The Hanford Nuclear Site in central Washington used to produce enriched plutonium for atomic weapons in the mid 20th century. Now it is known as the largest volume -208 million liters - of toxic waste in the USA. When regulators noticed that the underground waste tanks were corroded and leaking radioactivity into the groundwater, the cleanup effort included permanently sealing those ta in stainless steel containers. nks The major radioactive waste products 239Pu (ti/2 2.41 x 10f years), 9 Tc (tu/2 2.20 x 10° years), s0Sr (ti/ - 29.1 years), 1291 (ti/2 1.57 x 10' years), and 235U (t/2 7.04x 108 years) are considered "low-level" after they have decomposed to 0.1% of their original level. If the Hanford site stopped its production in 1970 C.Е., in what year will all of its nuclear waste be "low level"?
