Watch those Canadian Cat Scanners

[Biblio Bibuli]

Both of the today's Canadian articles below claim (and I quote):

"Some CT scans expose people to 250 times the radiation of an ordinary X-ray."

My question is .... is it because Canada uses older Cat Scanners, the ones that take five minutes to produce a single picture as compared to the newer ones that take only half a second to produce the same picture?

I think so.

"Some CT scans expose people to 250 times the radiation of an ordinary X-ray."

That's an abdominal Canadian Cat Scan that produces 250X the radiation. I have an iron stomach and gut so I don't care.

But I'm a Rene Levesque type smoker and thus have two lung Canadian CT scans a year as a precaution, and when I read in the National Post article that (and I quote):

"A single chest CT scan can deliver a radiation dose roughly equivalent to 400 chest X-rays"

....... that is like having 2.2 chest X-rays a day.

I'm scared.

I had a bone scan for an x-ray a few years back and the nurse told me it was around 50-60 x-rays (they inject some radioactive thing into your blood to get the images).

None the less, time to invest in some new equipment Canada... or private companies that actually want to invest in new equipment.
