Measuring Radiation. There are four different but interrelated units for measuring radioactivity, exposure, absorbed dose, and dose equivalent. These can be remembered by the mnemonic R-E-A-D, as follows, with both common (British, e.g., Ci) and international (metric, e.g., Bq) units in use:. Radioactivity refers to the amount of ionizing radiation released by a material.

The effect of a change in milliamperes (mA) on radiation output is seen. With 8 mA, the DAP is 785 mGy × cm² . With no other change in the exposure parameters or FOV, a decrease in mA to 4 decreases the DAP to 392 mGy × cm² . A decrease in mAs is associated with generation of fewer x-ray photons, which effectively reduces the radiation ...
