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

[eswed37]

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.

Joachimstahl in Czechia, not Slovakia...

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

[Ragnar1001]

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.

will uraninite explode if you incase it in acrylic?

[bsochettto]

How is this counter made/assemblated ?

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

[stephendonnelly88]

CPM stands for "Counts Per Minute". Similar to "DPM" (disintegrations per minute), CPM is used to measure how potent the radioactivity is.

Nice Uraninite sample. Check my video out for radioactive minerals.

[IHAntonio]

Is that saturation?

[stephendonnelly88]

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

[eswed37]

Please explain me the term CPM
