Cold-war nuclear test waste entombed there under concrete dome. Sounds like the dome has failed.
17?
8 You mean. 1+1+3+3 =8.
Or do you just start with 11 and then at two 3's to be inconsistent?
Plutonium 238 dumped there in 1957 has a half life of 50,000 years Sparky.
Chernobyl is still lethal after 40+ years.
If the containment vessel (concrete cap-dome on a coral-rock hole) has failed all those goodies will be blowing in the wind.
