Topic: Radiation Dose Chart

[daveeb]

I thought luminous dials were no longer radioactive, Clive?

they're not supposed to be but i reckon a few of the cheap chinese fakes could be a bit dodgy.

As an aside at the turn of the 19th century you could get "sodastream" machines that made you a fizzy radium drink , yum. 

Excellent chart by the way Sam, consider it stolen. 

[Clive]

We had a Geiger counter in the lab at which I used to work and it used to go into a frenzy if I placed my watch next to it.  But I think the radioactive substance was promethium 147  and not radium as was used previously.  They may well have changed to something less radioactive in recent years.  Wimps!!

Apparently the BBC Philharmonic Orchestra's instruments are now radioactive after their tour of Japan!

[Simon]

Well I'm blowed!

[Rik]

Or brassed off.

what, did they stand on top of the nuclear reactor?

It was also reported in a BBC Radio 5 news bulletin.

I bet they wouldn't have been popular if they had been playing Handel's Water Music.  Incidentally, I hear the water in Tokyo is now regarded as unfit for babies to drink due to radioactive contamination.  Tokyo is about 240 km (150 miles) from Fukushima!

[Simon]

It does now seem as though they may have been playing it down a bit.

I don't know everything I've heard about the radioactive release sounds reasonable.

But, even though the level is more than twice the 100 becquerels per litre experts say is safe for infants to consume, older children and adults are being told they have no reason to fear water from their taps

The radon concentration in an average UK house gives 20 becquerels per cubic metre.

The radon concentration in an average UK house gives 20 becquerels per cubic metre.

And the amount at which you are recommended to take steps to reduce the level is 400 becquerels per cubic metre i think (unless it's been reduced recently).

I should imagine much would depend on your body mass.  Smaller people (such as children) would be affected worse than adults.

[sam]

though the cross section of radiation encountered would be smaller.

Children are more susceptible as some organs are not fully matured and are more prone to chromosome damage. Younger adults are more susceptible than older ones as they have longer to live for the radiation effects to occur.
