You're right - there is a difference between a mRad and a mRem. However, in this case, they're equivalent:
There are several others places to cite, but for details see:
http://www.radford.edu/~fac-man/Safety/Radiation/chp5.htm where they conclude:
"In summary, the roentgen is a unit of exposure, the rad is a unit of absorbed dose, and the rem is a unit of biological dose. The rem is the unit that is used to measure radiation doses to personnel. For practical purposes, however, the roentgen, rad, and rem are essentially equivalent
for gamma and beta rays and can be used interchangeably. Commonly used subunits are milliroentgen, millirad, and millirem (mR), which are equal to 1/1000 of these units."

Correct. However, the ESE units do not take into account the "effective" dose to the skin. The skin has a multiplier of about 0.01 thus making 200 mR ESE equivalent to about 2 mRem effective skin dose.
