As a public service, I present the following simple page:
http://www.jlab.org/div_dept/train/rad_guide/rad.htmlRadiation is not found "in" things. It is not found in food, it is not found in milk, it is not found "in" anything. It can't be. Radiation is energy, and it is found coming out of things. Now this may seem pedantic, but it is important to understand.
When someone tells you that "radiation has been found in X", you should know right away that they either:
a) Don't know what they're talking about.
-OR-
b) Are trying to scare you.
It's also possible that both A and B are true.
Why do I say this? Because in the feeling of the general public, the term radiation is scary, and it is especially scary when it is unquantified. You cannot properly quantify the radiation found "in" something, because radiation is measured in units of energy, not in units of volume or mass. Units of volume or mass are what we would understand in terms of something found within something else.
Example:
"Active Ingredients:
Hydrocodone - 5mg
APAP - 500mg"
Now, let me come to my point: Sensationalism is worthless and irresponsible. The statement that "radiation has been found in X" is sensationalism. If we want to be informed citizens, let us focus on quantifiable, accurate information, and leave the hype to Faux Noise.
