What is a Rad?

Hi folks. When discussing radiation exposure, most of the radioactivity measurements are given in Bq/L or mSv. I was digging through some old newspaper clippings I have, and found some articles that hit the national newspapers in 1997. They discussed radiation testing in the 50's and 60's, and said a large percentage of the American population was exposed to 2 Rads of radiation, and specifically named Iodine 131. My question is, how does 2 Rads compare to what we are getting from Japan currently?

Well, that all being fine;

Well, that all being fine; as I said, does anyone know how this compares to the current situation? How many RADS, or percentage thereof, have we been exposed to?

The sievert (Sv) and gray

The sievert (Sv) and gray (Gy)

Despite the years of high-quality research reported in rems and millirems (mrem, 10-3 rem), the International Commission on Radiation Units and Measurements wants us to give up the rad in favor of the gray (Gy), a unit 100 times larger. Similarly, the rem is to be replaced by the sievert (Sv), again so that 100 rem = 1 Sv. So I will try to express all radiation doses in a single unit, the millisievert (mSv).

I believe it would be very

I believe it would be very hard to know what your exposure levels have been I don't know what you have eaten breathed drank.it would be different for everyone in America based on diet geography etc..maybe a brawn or someone smart could say how many gallons of milk u would have to drink to be exposed to 2 rads?it's a very complex equation when u factor in internal ingestion.

RAD - Radiation Absorbed

RAD - Radiation Absorbed Dose applies for inanimate objects. For General Beta-Gamma radiation, RAD equates to REM (roentgen Equivalent Man). These are both older, US measurements like pound and yards. They have tried to replace the US units with the SI (International System of Units), similar to metric system. See http://www.unitconversion.org/unit_converter/radiation.html for easy conversions.

Dose or Absorbed Dose:  Absorbed dose is the amount of energy that ionizing radiation imparts to a given mass of matter. In other words, the dose is the amount of radiation absorbed by and object. The SI unit for absorbed dose is the gray (Gy), but the “rad” (Radiation Absorbed Dose) is commonly used. 1 rad is equivalent to 0.01 Gy. Different materials that receive the same exposure may not absorb the same amount of radiation. In human tissue, one Roentgen of gamma radiation exposure results in about one rad of absorbed dose.
