The roentgen (symbol R) or röntgen (in German) is a legacy unit to measure radiation exposure.It was defined as the quantity of x-rays that produce 2.580 × 10-4 coulombs of charge collected per unit mass (kilograms) of air at standard temperature and pressure (STP): 1 R = 0.000258 coulombs per kilogram (Ckg-1) of air.. Terminology. Edit: thanks for the kind words, aldi. The SI unit for absorbed dose is the gray (Gy), but the “rad” (Radiation Absorbed Dose) is commonly used. Instant free online tool for gray to rad conversion or vice versa. In human tissue, one Roentgen of gamma radiation exposure results in about one rad of absorbed dose. The older unit of rad (rad or D) is exactly 0.01 gray and is now obsolete. Find more Units & Measures widgets in Wolfram|Alpha. 15,000 Roentgen is about 139 sievert's. Get the free "Convert Roentgen to Gray" widget for your website, blog, Wordpress, Blogger, or iGoogle. Also, explore tools to convert gray or rad to other radiation-absorbed dose units or learn more about radiation-absorbed dose conversions. As with sieverts and rem, one gray … Data should be separated in coma (,), space ( ), tab, or in separated lines. The measurement of absorbed dose in tissue is of fundamental importance in radiobiology and radiation therapy as it is the measure of the amount of energy the incident radiation deposits in the target tissue. The amount of ionizing radiation required to produce the same biological effect as one rad of high-penetration x-rays. unitsconverters.com helps in the conversion of different units of measurement like Gray/Second to Roentgen/Hour through multiplicative conversion factors. The SI bureaucracy, in what some see as an excess of zeal, has replaced the rad, rem, and Curie with, respectively, the gray, sievert, and becquerel.

As with sieverts and rem, one gray equals 100 rad. Roentgen definition is - of or relating to X-rays. The gray has a number of fields of application in measuring dose: Radiobiology. 8 sievert's is enough to kill even with medical attention. The raw amount of radiation that an object absorbs is expressed in eitherrad (customary) or gray (SI). Different materials that receive the same exposure may not absorb the same amount of radiation. 33 votes, 32 comments. The roentgen is being replaced with, God help us, the coulomb/kilogram.
