In radiation protection, the rem (an abbreviation for Roentgen Equivalent Man) is the non-SI unit of the equivalent dose, which is used predominantly in the USA.The rem represents the equivalent biological effect of the deposit of one hundred ergs of gamma rays energy in a kilogram of human tissue. The Röntgen equivalent physical (rep), introduced by Herbert Parker in 1945, was the absorbed energetic dose to tissue before factoring in relative biological effectiveness. The rep has variously been defined as 83 or 93 ergs per gram of tissue (8.3/9.3 mGy ) [13] or per cc of tissue. Nuclear radiation has a major effect on matter; since nuclear radiation has an energy which is very high relative to the energies of chemical reactions, absorption of nuclear radiation by matter causes many chemical reactions to take place. When the matter which is the target is living tissue, these chemical reactions cause serious injury or death. The U.S. Nuclear Regulatory Commission (NRC) was created as an independent agency by Congress in 1974 to ensure the safe use of radioactive materials for beneficial civilian purposes while protecting people and the environment. Roentgen Technical Inspection Pvt. Ltd. (RTIPL) is an ISO certified professional NDT company.

2011-03-25 As a result, one roentgen corresponds to 2.58 x 10-4 coulomb per kg of ions generated in air and an exposure of one coulomb per kilogram is equivalent to 3876 roentgens. Radiation exposures measured in industry (except nuclear medicine) often have comparable doses to one roentgen and the following multiples are often used: 1 mR (milli roentgen 2003-12-01 2014-01-30 According to the U.S. Nuclear Regulatory Commission, it would take about 450 rem (roentgen equivalent in man) to kill 50% of a human population from exposure over 30 days.

Ett dyrt, men mycket effektivt undersökningsinstrument är PET-kameran. Framförallt vid lungcancer är det bra att använda PET/CT-röntgen. Foto: Jan Lindmark. ”PET är bättre än andra röntgenmetoder, men den är inte humörbefrämjande.

To put into context how lethal that is, a fatal dose of radiation is estimated at around 400 rem (rem, or roentgen equivalent man, is a measure of the health effect of low levels of ionizing radiation on the human body). A total of 400 rem would be absorbed by anyone whose body is exposed to a field of 400 roentgen for 60 minutes.

Renografi är en funktionsundersökning av njuren där man studerar tidsförloppet för hur substanser utsöndras via njurarna till urinen. På nuklearmedicinska mottagningen utför vi en rad olika undersökningar för att få information om din fysiologiska funktion. Vi utför mätningar av njurfunktionen med kontrastmedel och nuklearmedicinska behandlingar, bland annat vid sköldkörtelbesvär. Former unit of ion dose, symbol: R. The ion dose of 1 roentgen is equal to the generation of an electrostatic charge unit by gamma or x-radiation in 1 cm3 dry air under normal conditions NMR eller nuclear magnetic resonance (kärnmagnetisk resonans) har funnit tillämpningar inom medicinen, speciellt radiologi. Av någon diffus anledning tycker man på detta område inte om att använda 'nuclear' så det har blivit MR eller magnetresonans. Detta har sedan blivit 'magnetröntgen'.
