What card is this?

[trag]

Yes and no.  Exposure to ionized radiation is a cumulative dose, so it would be relative to how much exposure you already have.  However, if you've had enough radiation already that this card would affect you, then you're already on your way out because you'll probably get more radiation from the sun by standing outside for about a nanosecond.

One of the points to Muller being a liar is that cumulative dose matters not at all. Low chronic exposure doesn't affect humans. It takes a large dose, >100 millisieverts in a short period of time --probably not longer than a month, possibly as short as a week.

The old theory which was not supported by evidence, was that insult to DNA accumulates. In reality, cells have a variety of repair and coping mechanisms (e.g. cell suicide) which resolve damage in less than a week.

Society is spending billions on radiation mitigation and under using medical diagnosis tools because of Muller's lies.

And as a result of those regs the chances of this card being in any way "radioactive" is nil.  No way the machine it was in or the operator console would have been on the wrong side of the shielding.

 

ionized radiation

Small note: that should be ionizing radiation, ie, something that can knock an electron away from a nucleus thus creating two ions (+ and -)

.... which, in turn, is quite different from the kind of radiation that can make something else radioactive.  That involves hitting the nucleus with a particle directly, making it unstable over the long term.
