Radioactive record cleaner

Recommended Posts

I remember when I was young a friend of ours had a small record cleaning brush that apparently was banned because it was radioactive. Does anyone know anything about this?

Staticmaster antistatic brush is still available from the US.  Polonium 210 source inside (somewhere there's an emoji for WTF, freaking terrifying, are they nuts?).

$89 US and still in stock...

At least it would be easy to find, as I would expect it to glow in the dark.  A lime green colour, like radioactivity is depicted on The Simpsons.

This was back in the 1970s. I'm wondering if our friend at that time who had this thing got cancer of the hand or something like that. I remember him joking about how this thing was banned.

I've never heard of an LP brush but I did have a 35mm film brush with the radioactive insert. At the time they said it was too weak to be harmful.

 

The static elimination only lasted a few years and the replacement strip was too expensive so I ditched the whole idea.

G'day all, such things were very popular in many household items in past years.  At least the zerostat uses a non radioactive piezoelectric approach to static removal and mine works fine.  This is a interesting website.  https://www.orau.org/ptp/collection/consumer products/consumer.htm  Regards, Felix.

Have granite benchtops? they're radioactive too! Very low level.

G'day all, smoke alarms do worry me actually.  Years ago Wormalds used to install ones in Government premises and the like using rather high activity Radium 226 and were very radioactive, and in my opinion not safe. 

 

These days smoke alarms for sale tend to use an Americium  isotope which is safer but is still a potent alpha particle/ gamma ray ionisation radioactive source.  The 'optical' smoke detectors are now more recommended by authorities like ARPANSA.  Regards, Felix.

Have always wondered about that.

 

Couldn't shut mine up even after a dismantle and clean, so .... not there now.

Very cool stuff in the links here. The polonium 210 brush is only an alpha particle emitter and alpha particles don’t penetrate far like gamma rays. It won’t even penetrate through the dead skin cells on your hand or a few CM of air. Still scary from a contamination perspective if the brush was broken or tampered with (you wouldn’t want to ingest or inhale any polonium!) The idea is that the radiation strips the electrons from the air near the brush which then makes the air soak up any static charge on the record surface. Very cool.
