This is a work in progress. Countries with zero counts have not been screened.
Counts following country name indicate the number of readings taken in that country. An image of the radiation detected
will be found directly after that number. Caves are indicated with small green dots or yellow pushpins.
Scale bars indicate counts per minute and vary considerably from plot to plot.
Cavers are invited to send soil samples from caves that are suspected of being contaminated. Contact peter@well.com for details.
