Radiation intensity (mainly from cosmic rays) on the top of the Mt Buffalo National Park, Victorian Alps, Australia. Shown by comparison are measurements in my home, office and railway station (U/G loop).

Measured with a RM-60 micro-Roentgen radiation montitor from Aware Electronics Corp, P.O. Box 4299, Wilmington DE 19807, U.S.A.

If you think that is bad, you should see the radiation intensity at 10,000m in a commercial jet aircraft.
