I don't understand why medical equipment manufacturing companies spend millions on all kinds of largely useless idiot-proof labelling outside of their machines and manuals, but won't make the effort to implement simple, redundant interlock fail-safes to prevent radiation and other hazardous overdoses.

This peculiar problem is not limited to the medical equipment industry alone. I've seen the same problem with industrial equipment, as well.

We need to see the: “ARE YOU SURE?” prompt when outside a normal dosage.

Over the years, I have read a great deal on a series of deadly malfunctions on one particular model of radiation machine: The Therac25.

A cautionary tale for anyone designing computer-controlled stuff.

I’ve seen why. Some idiot in management decides it is easier for his career to put “don’t do that” in the user’s manual than to make it impossible for the user to do that.
And the FDA accepts it as a job well done.
