On July 16th, 1945 the first atomic bomb was detonated at the Trinity Site in Los Alamos New Mexico. The blast was equivalent to 18,000 tons of TNT. It melted the surface sand near the tower where the blast occurred, turning it into a light olive-green glass-like substance. When it cooled it solidified again into a substance that scientists called "Trinitite".In 1952 the site of the explosion was bulldozed over. It is now a National Historic Landmark district and in 1966 it was listed on the National Register of Historic Places. Since 1952 it has been illegal to remove anything including Trinitite from the blast site. The Trinitite particles that we are selling are from a group of Trinitite collected by Dr. Pray before the site was bulldozed. It is authentic and can be verified by gamma spectroscopy.The tiny particles that we sell are mostly smaller than the head of a straight pin and are supplied in a glass vial (just a few particles at the bottom - not a jar full. Study them under a microscope magnifier or one of the inexpensive digital microscopes that are popular now. The photo you see on our website was taken with a Canon G16 digital camera with a basic lens.Own a small piece of Atomic and United States history. Comes with an authenticity certificate. Note: This sample causes no reading on our most sensitive Geiger counter, however, you should not touch or eat it.
Jordan Dosimeter Charger Model CD V-750 Model 5A was designed to charge all common Quartz Fiber dosimeter pens such as the CD V-742 (not included). It operates on 1 "D" battery (not included) and by adjusting the knob you could adjust the hairline in the pen to zero. We do not test them and are selling them "As Is" used. These do come with an original manual.
