This is a question The Dirty Secrets of Your Trade

So, Television is a hot bed of lies, deceit and made up competitions. We can't say that we are that surprised... every job is full of this stuff. It's not like the newspapers currently kicking TV whilst it is down are all that innocent.

We'd like you to even things out a bit. Spill the beans on your own trade. Tell us the dirty secrets that the public need to know.

Radioactive materials do not glow in the dark,
unlike in the opening titles of the Simpsons, The glowing which is sometimes observed is either due to a fluorescence effect when charged particles given off by decaying radioactive materials interact with a phosphor or the like, or it is caused by Cerenkov radiation.

Cerenkov radiation is the blue glow which comes typically from pools of water holding radioactive materials and is caused by the charged particles given off by these materials travelling faster than light in that medium (water). It is the optical analogue of the sonic boom.

Not so much a dirty secret as a science lesson. Sorry. I got all carried away there.
