DRSB-88 Geiger Counter on a Smoke Detector Source

Smoke detectors mainly emit alphas, which do not penetrate the DRSB casing. Just a little gamma.
Not a good demo, actually, you missed the point.
-
Just so you know americium, that radioactive source you have there, release mainly alpha radiation. Of course there is some gamma as well, but your DRSB-88 isn't picking up a lot of the radiation that source is giving off.

What's with the 717? It couldn't detect anything anyways, short of a atomic blast or meltdown.
-
why do you have a survey meter there? i don't think it can detect radiation sources that low
-
Americium has an alpha decay mode. Alpha radiation can be very dangerous - If a particle is ingested, it will bounce around in the body whilst constantly ionising tissue. Not good.

hello, can you please tell me where you bought this from? i cannot find it anywhere. and i really want to buy one.

Beta is also present in low doses with AM-241

His geiger counter is designed to detect only gamma rays. I saw his other video and its quite obvious that this is the case. With the beta shield closed on my CD V-700 and Ludlum Model 3 i get just about the same number of clicks from a smoke detector source. Americium's main radiation is alpha, but it also emits a small amount of gamma rays which is creating the clicks here in the video.
Smoke detector sources are actually very active. I can pick them up from a foot away, behind a bunch of clutter, with my DSRB-01. I have 2 DSRB-01 and 2 DSRB-88s and the 88s seem totally useless - on a radium watch dial, the 01s make a crunching sound and flash "WARNING" but the 88s don't change at all.

@dojomojomofo I know what's going on my Chrismas list.

wow u r getting background not the americium from the smoke detector u probably too the wrong part out of it

No, background only results in a couple counts per minute. The meter is designed for higher levels of radiation.

I'd like to see the big yellow one operate.

He he. If the needle on that one ever moves, you are already in danger.
But I did test it with an x-ray machine once and the needle went to 0.5r/hr!
