Another random search quest- this time searching Scavenger camps for dead bodies. Not the usual sort of dead bodies, but ones surmounted by little magnifying glasses.
These people died of a serious baceterial infection. The more you find, the better SAM can narrow down the disease's orgin. So, keep finding. Find the last and SAM will feed you a navpoint.
This turns out to be by the northeast monolith site. Cruise over to be attacked by radioactive bugs, but not the cool kind.
Deal with them, then track the infection source to some discarded radioactive waste.
Interact with the stuff to neutralize it, stopping the outbreak and reaping a small Viability reward.
