The exposure rate of an activity of 1 millicurie (mCi) measured at 1 centimeter (cm) is called - ANS - The exposure rate constant (ERC) For positron emitters, the exposure rate constant (ERC) is about 6 R/h per millicurie at 1 cm. The exposure rate of a 10 mCi dose of F-18 is approximately six times greater than that of a 10 mCi dose of Tc-99 m at a distance of approxi- mately 8 inches. Quantitative bias that refers to the underestimation of counts density which differs from what th...
