The mache (ME) is an obsolete unit of concentration of radioactivity which was originally expressed by a concentration of elemental radon per liter of water. One mache unit is equivalent to 3.7 x 10-7 curie or 13,760 becquerel per milliliter.
History and etymology
This eponymous unit was named after Heinrich Mache (1876-1954), an Austrian physicist 1,2.
