Pitchblende is an uranium-rich uraninite mineral from Jáchymov/Czechoslovakia (Joachimsthal) with a composition that is largely oxides of uranium (UO2, UO3). It has a natural radioactivity due to uranium and its decay products (radium, radon ...).
By a simple Geiger Mueller counter the radioactivity is demonstrated by optical and acoustic signals. It can be recorded on a redisigned calculator if a certain distance between mineral and counter is kept.
Pechblende ist ein "Pech-schwarzes" Uran-Mineral aus Jáchymov/Czechoslovakia (Joachimsthal). Es besteht im wesentlichen aus Uranoxiden (UO2, UO3). Es besitzt eine natürliches Radiaoaktivität wegen des Urans und seiner Zerfallsprodukte (Radium, Radon ...).
Diese Radioaktivität wird mit einem einfachen Geiger Müller Zähler über akustische und optische Signale vorgeführt und durch einen umgebauten Taschenrechner gemessen.

  • if its so strong radioactive why you holding it in your hands isnt that dangerous

  • I do NOT hold pitchblende in my hand.

    The mineral is closed in a plastic pouch.

    The distance to my finger tips is nearly 10 cm. Compare the counts/minute when the same distance is between the mineral and the counter.

  • What is the CPM rating of the sample of Uranium shown in the video?

  • Please explain me the term CPM

  • Drop that thing and call the clean up guys!

  • Affirmative...its not from slovakia but from czech republic...greetings from slovakia :-)

  • hmjungs aus De? Bin total einsam wer hat lust zu schreibn

  • Kein uranium sondern Uraninit und das wird als Pechblende bezeichnet oder im englischen als pitchblend. Es ist legal und du kannst es bei Ebay kaufen.

  • Joachimstahl in Czechia, not Slovakia...

  • wááá you use uranium? and this legal? ha??

  • will uraninite explode if you incase it in acrylic?

  • How is this counter made/assemblated ?

    Did you do it yourself from separate materials (obviously the calculator part, yes).
