Did Bob's I.Q. just drop 50 points?
In the soft sciences, that phenomena is called the Baseline Radiation
Level.
No Shit Sherlock, ... there is a Radiation Baseline.
Sorry Bob, but YOU are WRONG while MOI is Correct. Radiation released
during the World War II era made 100% of Europe radioactive. In other
words, the atomic bomb associated radiation contamination rose
Europe's Radiation Level above the previous Baseline level.
In other words, Dumb Dumb, scientists zero out the baseline level,
whatever it might be, in order to measure increases in whatever you
are measuring.
Here endeth Bob Officer's Science Lesson for today.
Boy Bob Officer, YOU are quite the Ignorant Dumb-Ass. :)
