Comment Comment by krasin I found the specs for the fuel source: https://upload.wikimedia.org/wikipedia/en/e/e9/SNAP-19C_Moun...The high-power unit had 300 grams of Pu-238 in 1965. Given its 87.7 years half-life, only 187g of Pu-238 remaining. It's very hard to do much damage with this amount of radioactive material. parent krasin 9 months ago
