Good explanation

Yikes. Your explanation is okay but flawed. Especially with the last part of this video calling out the health hazards of radioactivity. Do you *REALLY* think radiographers don't know the safety of radiation or are going to let the public near the source? If you were to explain "barricades", as well as the amount of Roentgen (or REM) the public should be receiving from radioactive material, then you wouldn't have to worry about health hazards. But in case anyone wants to watch this and ask, here's some more insight: Let's start with this: Radioactive measurements are in *Roentgen* (R), *milliroentgen* (mR), *Radioactive Absorbed Dose* (RAD), *Roentgen Equivalent Man* (REM). Although they're the same in measurement, the difference is that RAD deals with materials, and REM deals with the human body. You can think of R and mR as the "basics" (and also: milli = 1000, so 1 R = 1000 mR) So the main safety objective for radiographers is to provide the public with a way to spot and alert them of the radioactive material. This is where *barricades* come in. These are placed out, starting from the source location, of a certain amount of feet to provide alertness to both the public and the radiographers. For example: - A restriction area is placed at 2mR/h @ 1 foot. Please note: The barricade is NOT placed at exactly one foot away from the source. We use detection equipment to indicate where the 2mR is. The 1 foot is just there for reference (Ex. Companies using the Imperial system VS Companies using the Metric system). I know this video is 2 years old, so pardon me for this long comment. I just wanted people to know that as long as you're being *SAFE* with radioactive materials, then there's no need to fear for your health. That's what radiation safety classes are for.
