Maybe they'll finally find the nuclear device lost on Nanda Devi, that has the potential to - *checks notes* - poison North India (via the glacier that feeds the Ganges).
How large is the amount of plutonium in there? I highly doubt that it has the claimed potential.
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.
I really fail to see a problem with these tiny amounts of non-brittle material embedded into a solid case. It's still very dangerous, but it's locally dangerous (meters away), not at the scale of whole countries.
