APAKAH MAKSUD ROENTGEN EQUIVALENT MAN dalam CORSICA?
Lelaki bersamaan Roentgen
Setaraf dengan roentgen pada lelaki adalah CGS yang lebih tua, unit dos bersamaan, dos efektif, dan dos komited. Kuantiti yang diukur dalam rem direka untuk mewakili kesan biologi stokastik radiasi pengionan, terutamanya kanser yang disebabkan oleh sinaran. Kuantiti ini adalah purata wajaran yang kompleks bagi dos yang diserap, yang merupakan kuantiti fizikal yang jelas diukur dalam rads. Tiada penukaran penukaran universal yang boleh diterima dari rad ke rem. Rem ini ditakrifkan sejak 1976 sebagai sama dengan 0.01 sievert, yang merupakan unit SI yang lebih biasa digunakan di luar Amerika Syarikat. Sejumlah definisi awal yang berlaku pada tahun 1945 diperoleh daripada unit roentgen, yang dinamakan sempena nama Wilhelm Röntgen, ahli sains Jerman yang menemui sinar-X. Akronim kini menjadi artifak sejarah yang menyesatkan, sejak 1 roentgen sebenarnya mendepositkan kira-kira 0.96 rem dalam tisu biologi yang lembut, apabila semua faktor penimbang adalah sama dengan perpaduan. Unit-unit rem yang lebih lama berikutan definisi lain adalah sehingga 17% lebih kecil daripada rem moden. Satu rem membawa dengan itu peluang 0,055% akhirnya berkembang menjadi kanser.

Roentgen equivalent man (REM): The unit of dosage equivalent from ionizing
radiation to the total body or any internal organ or organ system. A millirem (
mrem) is 1/1000 of a rem (40CFR141. 2-91, see also EPA-89/12; DOE-91/04).
