Where can I get a battery alarm clock which has hands that can be read in
the dark?

Extravagant! I'd check Poundland first.

Ive seen them but you have to push a button to make them light, post
back if you find one that just stays lit, I just got a Weather
thermometer with clock at HD, but again its dark till you push the
button but it has an RF set clock so it never needs setting.

they don't use radioactive luminous paint any more, so 'glow in the
dark' watches and clocks are a thing of the past.

I've come to the same conclusion. The paint often *looks* like the
proper luminous stuff, but it isn't. The clock I bought recently has
some kind of fluorescent paint that glows green for a short while after
the light goes out, but not long enough to be of much use.

Quick look in the Tesco Direct catalog (it just happened to be the
nearest) page 444 at least 3 of the 4 across the top of the page have
luminous hands. The LH one looks to have luminous figures as well.
The RH one dots for the hours.

The non-radioactive paints need "charging up" with decent light, kept
in room with the curtains closed or only brief artifical light source
they are dim. The best way to charge up these paints is with a UV
light source, say a bank note light or one for making the invisible
security pens visible.

There are still radio active glow in the dark things in the market.
Mostly emergency signs and the like, they use tritium IIRC rather
than radium.

The ones with crappy luminous paint are easy to get from the usual
places. If you want one that really works though, you'll need spend some
money and get a tritium one:-

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=220571309038

A bit of digging might get you one closer to home. try Googling for
Luminox, Traser or Tritium

Cheers,

Colin.

There are alarm clocks with tritium dials. Did not google far but they

look pricey:

Beta particles from nuclear decay are harmless.

I've got one of those. I tried every room in the house before I found
somewhere the numbers would show up! Very accurate though...

The term is phosphorescent. Bit here on the topic.

Robert

you might still find an old one, but then you get to put up with
clockwork's inaccuracy and need for incessant winding.

To stay lit permanently would run down the battery too quickly, so
that's why you have to push to get it to light.

Not completely. Bad if source is ingested, bad if source is inhaled in
form of anything that sticks in lungs or is absorbed into the body from
lungs. OK if in a closed container and low energy, as is the case with
tritium.

Yes but unlikely and does not compare to the old radium dials that

caused cancer to the women painting them on.
