Me & my Pyrochlores

I am hold plumboMICROlite from Ploskaya Mt. ( http://www.mindat.org/loc.php?loc=2670 ) in the right hand and pyrochlore from Tatarka Range ( http://www.mindat.org/loc-20373.html ) in the left one. The pyrochlore is completely nonradioactive (it give only 20 μR/h), while most of pyrochlores larger of 1 cm size usually are more radioactive, than this huge crystal. The plumbomicrolite crystalline cluster is about 1.5 kg and give about 700 μR/h due to content of uraninite microinclusions. By the way, this was the main reason, why I obtained it so simply. ;) And, of course, my mineral cases as background.
