December 15, 2024September 14, 2024by Alexander Johnson Units for dose equivalent are the roentgen equivalent man (rem) and sievert (Sv), and biological dose equivalents are commonly measured in 1/1000th of a rem (known as a millirem or mrem). Table of Contentsshow WebIn direct assays, the doses of the standard and test preparations are “directly measured” for (or until) an “event of interest”. Response is fixed (binary), dose is random. • When an event of interest occurs, e.g.. the death of the subject, and the variable of interest is the dose required to produce that response/event for each subject.
