Radiation sources

Post by dolphinscales »

Just curious to how many schools out there have radioactive sources at their school and if so what

We have alpha (polonium), beta(strontium), and gamma(cobalt 60S), they are very small amounts,we got them from serrata.I wrap in lead foil and store in a locked cash box. they dont get used all that often

We also have gamma (Cobalt 60), alpha (Americium 241, radium 226) and beta (cesium 137).

We have caesium and americium - the older needle type that would have come with our cloud chamber, circa 50's??, and they still work well for that experiment.

Also 'newer' disc type versions of radium, cobalt and strontium, that look like the ones you can buy new, but ours must be over 10 years old, and the cobalt gives very little reaction.

We have similar, but what concerns me is
Is there some licencing to have these and some accounting because apparently 1 of our sources went missing ( according to a teacher ) and as they were not individually listed just "raidoactive isotapes" I can't say yes or No And don't want to take responsibility for these without some better system

Ocker - ours were just bundled into a cash box, and obviously had been like that for years.

I've organised and labelled everything, researched and printed out information, learnt out to store them, etc.

Now I'm the one who gets them, mostly helps with the prac, then returns them each time.

Check your CSIS, there's some good info in there: Section 3 (curriculum support documents, pg 37)

We have the alpha, beta, Gamma sources.. I keep them in a container I bought from Serrata... I asked them about the safety and asked for a MSDS for them.. they assured me that the samll amount we buy, and the few times they are used, they are not a Hazard... my HOD agreed.
I also found out from him that the alpha source only lasts about 6 months ..... after that you get no response... so I am now only going to purchase that just before we are about to use it!

The radioactive sources allowed in WA schools are listed in the DET Science Laboratory Manual in the Physics section.
I have mine stored in a radioactive pot that I purchased when I bought the sources and that is locked in a cash box lined with several sheets of lead in a locked store room.

Ours (americum, caesium and cobalt-60) is kept in a chemical cabinet, labelled 'radioactive", and is locked at all times and only one person who knows where the key is, ME!

This is quite an interesting topic - I was just in the Physics store - I call it my bones and rocks room and looked up at the cardboard box labelled "Radioactive - store 1 metre away from other materials" and wondered what was in it and what it could be doing to my bones and rocks. Perhaps I'd better have a look!

Hello Pam!
Fortunately I made it out of the bones and rocks room alive! Liz will be pleased to know I carefully read page 37 before heading downstairs.

Donned disposable gloves and my kryptonite tie dyed lab coat and grabbed hold of the cardboard box.
Fortunately it contained a locked metal box (with key in the lock of course!) among other things like a pile of aluminium and lead foil, someone's notes on taxonmy, a petri dish, a brass rod, some plastic tubing and a large metal spring ????

Inside the metal box was more foil and some radioactive sources - 6 disc thingies and two rod looking thingies (love this technical terminology).

There was an old typed label on the box - as in on a typewriter it was that old - that indicated what should be in there.
Generally relieved that the baddies were in a metal box I have left them there to await more detailed cataloguing (Lizzie B style).
Thanks for your thoughts! :)

Radioactive source storage

Post by ri »

Hi All,
does anyone know if there is a safe storage box for radioactive sources out there yet??
We have always used a petty cash tin lined with lead, however upon testing the box with a geiger counter, there is not much change in the reading from the unprotected sources.
Surely we deserve a proper, safe storage box to protect ourselves.....
In the meantime I keep the little treasures as far away as possible from the prep room.

WOW! We don't have any & I'm so glad! I love my teachers - they are so safety conscious!!! :wub:

All that OH&S effort to store & handle... for such a small use...! :yuck:

Be careful everyone!

I decided NOT to have any radioactive sources in our school.

And on this one, what I say, goes!

As I remember may years ago, I took a geiger counter to the outside of the lead box that a schools radioactive sources were stored in.
The geiger counter was registering some serious clicks. compared to the natural background... not just with the Alpha particles either! as was the the shelf where it was stored.

And those were the standard storage... each sorce in an individual lead foiled container, and then all in a lead lined storage case.

As far as I am concerned, There are enough radiation sources in our world , natural, leakage etc without bringing more of them into my work area! :crazy: 8O

Not for this little ducky :!:

If the sources are stored correctly in the lead.... where do you store the lead storage case? Does it need to be kept in a special area?

Thanks

We store ours in a locked metal box in a locked cupboard in the physics lab (which is locked when not in use)
