Geiger Counter Demonstration

[BLynchCAN]

What ?

[ggabe005]

Test mayonnaise and pepto bismol with your geiger counter!!!! you will be shocked!

[guymark]

If you pull the camera back just a smidge and put it down, it will be less jerky and may be possible to focus it a bit too. It looked interesting but other than a good shot of a table and your wrist, it was hard to see what was going on.

[bacabu30]

where did you procure the radioactive material?

[BrianSouvannarath]

wait what is that stuff on the chair

[Doggieman1111]

that's a lot of beeping son

[nepssis]

That isn't geiger counter. It's semiconductor dosimeter. Not same.

[stephendonnelly88]

Um, It contains a Geiger-Müller tube; therefore, it is most definately a geiger-counter. It can function in the capacity of a digital dosimeter, but it reads background radiation using a geiger tube.

How could a 10 year old get nuclear matieral

[stephendonnelly88]

Not very easily. Of course, I really would know, since I'm not 10 years old... ;-)

[MattRaizoku]

@stephendonnelly88 easy you can buy this stuff of the internet, its under specific amount so it is legal.

[Huffdev]

@Greener262 so why did you call him a 10 year old?

[Outlander11]

Jezzzz... hold the camera still!

[shvets007]

))) ага просто обьектив мылом обмазали))

[KarbineKyle]

I have the same GM Counter. I hear the alarm going off, and I don't know if you know this, but you don't have to worry about the alarm, if you go to "Threshold" and set it to 0.00µSv, It will not auto turn off in 5 minutes if you do this AND The alarm won't go on! =) Reset or turn off to go back to standard settings. You can take the lead plate out too, if you want... These are great little digital GM counters. I have one, and I see you have United Nuclear products too! I do too! Nice Vid! 10+!

[lfstweak420]

What the heck? If you can get hold of such materials that means you could make.... :X

[stephendonnelly88]

I cannot make anything that would actually be reasonably dangerous with the radioactive material I possess.

Nor would I ever dream of even trying to do or make anything dangerous with radioactive material.

[Mangledlikesj00ce]

Nice!

Out of curiosity, what is considered normal reading from a gieger counter, just from normal atmospheric radiation?

[stephendonnelly88]

In my opinion, normal background radiation should not exceed 20 micro-Sieverts per hour. However, the Kiev-based manufacturer of my Geiger counter claims that the normal background radiation is anything equal-to or less than 30 micro-Sieverts per hour. The Sievert is the SI unit of measurement for dose-rate in relation to how it affects human biology (similar to the RAD).

[Mangledlikesj00ce]

Thanks.

[skunkgecko]

I personnaly doubt this, since 20µSv per hour gives you an extremely high total of 20 x 24 x 365 = 175mSv per year! Normal are however only about 1-2mSv per year.

Where I live, I have about 0.13µSv per hour what gives me a total of about 1.1mSv per year. 175mSv per year would be about 160 times my average yearly dose...!!

[stephendonnelly88]

Where I live, I am only measuring around 0.07 uSv per hour. I too, would find it rather alarming should I ever find out that I was living in a place that measured around 20 or so uSv per hour.

However, the "safe" figure of "not more than 20 uSv per hour" is merely one of the many, many rough figures I have heard as being the "normal level of background radiation." Admittedly, it does seem to be a bit high on the "normal" spectrum... :-)

[Librophon]

You omitted the comma, the values must read

0,20µSv and 0,30µSv (or Gy)

[stephendonnelly88]

Correct. Thank you. :-)

[respubliklenina]

Have good luck with your studies in Chornobyl Ukraine, ... I make joke about other video here.

[stephendonnelly88]

Haha! Thanks for watching... :-)

[Barthek88]

Turn on autofocus in camera next time :)

[nitrex]

I have a Geiger counter. But what you got looks more like a Dosimeter. Anyways great.

[stephendonnelly88]

Well, technically, my unit is both. It is a true Geiger Counter, since it uses and actual GM-tube, but it also has a function which allows it to monitor accumulated dosage.

[ub40fx1]

r those materials your testing with safe to handle?

[stephendonnelly88]

Yes, they are all complaint with the NRC Exempt-Quantity rules.

It would be unwise to carry these items in your pocket all day long, but they do not cause abnormal levels of radioactivity from a distance that is 5-6 feet or greater.

The bigger danger would be from somehow inhaling or ingesting the small dust or fragments that can break off of the ore samples.

[nitrex]

Yes they are safe to handle because the radiation is not that harmful , some ores go from 150 cpm to 40,000, the highest is 80,000. Ores are safe to handle and touch but you must put care to it that you don't play with it or even let kids touch it. Of course wash your hands when you done. Over all the radiation is safe if you do not over do it or sleep near it all day.

[rkodvl]

is a Geiger counter cheap?how much?

[adamoles]

about $50 for very old (only gamma/X radiation) to $400 for newest and the best (a,B, gamma, X, n radiation)

[wiccashaman]

any where from $45- on ebay i've seen one for $1000
