Do tell us, but a it's lot more than a restaurant per waiter.

What relevance does that have? Per owner might have some relevance.

And the number of dentists who go bankrupt^ is exceedingly small

They do say a dentist will never go broke practicing dentistry.

See, you do understand.

It doesn't mean they make a fortune.

My point was it is possible, not even that difficult to open a small
business and compete on income with a dentist.

Sure it's *possible* to win tattslotto too, but hardly relevant.

Silly statement really. The chances of a restaurant making as much as a
surgery are extremely good. Do the maths, a dentist might bring in $300 an
hour average and bill 30 hours a week for 48 weeks of the year for a total
of $432,000. This is a pretty optimistic figure as a dentist has a lot of
work to do besides be in the chair + they get cancellations. Most of the
surgeries I've been to have 4 or 5 staff per dentist, so 4 x $35,000 is
140k. Subtract $10k a month for running costs and paying off expensive
equipment and you're left with $172,000. And I think the initial income is a
fairly optimistic figure, if he spent 30 hours in the chair he'd be at the
surgery 50 hours per week minimum (he has to run a business also remember).
The staff figure is probably low too as these are trained dental nurses and
there's workcover, super etc. It would be fairly easy for the figure to get
closer to $100k.

On the other hand compare the full range of restaurants from your cafe on
the corner to mcdonalds (they started off as a small business too).......

I think you'll find that high energy radiation/particles will discharge flash and
EPROM memory cells over time. If the micro in your key is a ROM micro this isn't a
problem, however the rolling code will be stored in EEPROM.

Also, remove power (the battery) whilst doing this. The X-ray may induce malfunctions
if power is applied at the time.

Simple question. Will xrays damage electronics? Say if I was to xray the circuit in
my car key?

Thanks,
Mike

Thanks for all the replies. I haven't done my keys because my car won't open
without the electronic bit but I have been doing the phone quite a bit. I
think I'll use something non electronic from now on
