tissue or matter

the article states "converts between the amount of ionization in air (roentgens) and the absorbed dose in tissue (rads)". But rad is not a measure unit for absorbed dose in tissue, but on matter. Probably the sentence should be reformated as: "converts between the amount of ionization in air (roentgens) and the absorbed dose in matter (rads)". When speaking of tissues, need include the equivalent dose (Radiation weighting factors WR) for tissue, like in Sievert and rem do, and never use rad (and Gray) to avoide confusion.--Efa (talk) 12:16, 17 July 2014 (UTC)[reply]

As you say, rad is unit for measuring absorbed dose in matter, and tissue is matter. Rem is the unit for measuring Effective dose in tissues; it is equal to the dose measured in rads multiplied by the Relative biological effectiveness of the radiation. So going from roentgens to rems is a 2-step process. First convert to rads, then convert rads to rems. Rwflammang (talk) 22:55, 27 October 2015 (UTC)[reply]
