a geger counter type alpha ray detector is not very useful because alpha rays are stopped by a fairly short distance in the air
alpha radio activity is not dangerous by rays sent at a distance: it is especially dangerous when we breathe or swallows radioactive dust ... even if these rays have a short distance of action, when we have them inside the body it's been ravaging a long time
radio activity measurements are complicated, and above all complicated because we do not have radio active material on hand to try
it's easy to check a voltmeter because you easily have cells and batteries but how to check radio activity measurement equipment if you have nothing radio active
it is a little what makes the price of this kind of material: to sell it seriously you must know and be able to verify it

Excellent.
But you piss me off. Now that the store is friendly, I walk around and see that you have capacitors.
You have the one I needed two weeks ago, for the engine of the ash screw on my boiler, but you sell it 9 € while I paid the same 34 CHF ...
EDIT: On the other hand, small error in the statement:
Specifications
capacity: 25µF
dimensions:
D: 90 mm
L: Ø45mm
frequency: 50 / 60Hz
voltage: 450VAC
dissipation (tg d = 1 / Q): <0.004 (100Hz, 20 ° C)
temperature range: -25 ° C to + 85 ° C
I think the length and the diameter are reversed (or vice versa)
A +;)

Trying too hard to get into the mold, it ends up looking like a pie.

The capacitors are only on the shop since November 9 not before ...
Uh 34 CHF = 34 * 0.92 = 31.28 €?
ps: thank you I will correct the description actually I reversed ...

Come on, courage Christophe, I just added the banner of the Econological Shop on all the pages of my new cultural information site
www.caroloo.be
strictly reserved for "non mainstream" cultural news
- taking place in the Charleroi region
- or concerning carolos in exile
to isolate them from the din of the media background of people who have money!
other sponsors welcome!
Linguist's corner:
Charleroi was founded in 1666 by the marquis de castel Rodrigo who built a fortress there on the site of a small nail-making village called "Charnoy". In honor of the reigning King of Spain, he named it
Charleroi
The inhabitants of the Charleroi region are therefore the Carolo Régiens
in short, "carolos"
hence the name of the site, "internetized" in the manner of wanadOO, YahOO, etc: carolOO.
Readers interested in the cultural life of the area can also profitably consult the fessebouc page: caroloo.be ( https://www.facebook.com/Caroloobe-1682 ... 4/?fref=ts )

question
hello about a product from the shop,
I wondered what that meant,
the 2 and 5 liter stainless steel presses, I saw that you can press a lot of things, but when I saw grass too, I said to myself, what is it to do, pressed grass to make it dry and to heat as in Africa (in any case the idea is the friend I do not know if the pressure will be enough), or else squeezed grass to extract the juice and drink fresh grass juice.
so if the grand chief of the shop could answer me, thank you Tof.
and superb the new shop.
ps, I did not want to put my question in humor sometimes that it is not humor.

Uh great chef great chef ... no huh, little chef suits me better lol
Otherwise good question.
It's very simple: it is in case you make infusions of herbs in fact ...
You prepare a decoction, you let it "massage" and you squeeze.
ps: your order left yesterday, with some small gifts in it
