Nuclear Chemistry

I have seen a bunch of reviews of the DRSB-01 and one or two of the DRSB-88 and felt this little guy deserved more attention. Here is my DRSB-88 in action

Yes some beta and gamma can go throw lead, you just need more of it though. However you should never use a lead shield for beta radiation, because it will release X-rays, the reason is because when Beta hits a targeted metal, not all metals but some including lead, it releases X-rays due the the sub-atomic particles and there property behavior

Yes that is true. The source I used lead on was a pure gamma emitter so the risk of x-ray exposure was rather low.

this was in that chem lab

you were wearing your cool outfit

Now, add the lead!

[Ch3mG33k]

Haha. Funny...

Great job wearing sunglasses when it wasn't sunny out, looser.

k thnx

[sciencoking]

hmm about 70 dollars... ebay :-)

[atomic7732]

how much is it i might wanna get one of those!

[sciencoking]

oh thanx for the tip i´ll search some iron in my grandfather´s metal chaos

[sciencoking]

hmm it´s a piece of pitchblende that emits about 600 uSv/h

and about 30 go through 2 cm of lead

that HAS to be gamma

Well, you can shield it with aluminum or iron and then coat the end with lead or add another layer of lead. But i normally just shield them with any metal case, ores don't emit a lot of gamma rays, so you're safe, but of course if you have have gamma emitter then its best to use some lead, lead doesn't completely stop gamma, it just decreases the ray.

hey nitrex

i´ve got some really really strong radioactive stuff and i managed to shield it pretty well, but the first shielding layer is lead so your X-ray effect is pretty strong.

is it possible that those x rays mostly go though the lead?

what should i use as first shielding layer to reduce the x radiation?

and will that decrease the radiation that comes out?

[sciencoking]

hmm the RKSB i have doent klick but it counts the pulses and displays it

[nitrex]

True, but Gamma doesn't give off an X-ray as a lead target, only Beta, but if the emitter does contain small amounts of Beta like you said then you should receive small doses of X-ray.
