//www.medicinenet.com/sleep/article.htm">sleep: REM sleep is the portion of sleep when there are rapid eye movements (REMs). Dreams occur during REM sleep. We typically have 3 to 5 periods of REM sleep per night. They occur at intervals of 1-2 hours and are quite variable in length. An episode of REM sleep may last 5 minutes or over an hour [..]

"unit for measuring radiation," 1947, acronym of roentgen equivalent man.

One of the two standard units used to measure the dose equivalent (or effective dose), which combines the amount of energy (from any type of ionizing radiation that is deposited in human tissue), along with the medical effects of the given type of radiation. For beta and gamma radiation, the dose equivalent is the same as the absorbed dose. By cont [..]

A unit of absorbed radiation in biological tissue. Rem is equal to n times the number of rads, where the factor n is dependent on the type of radiation which is being absorbed. Rem is also an acronym for rare earth metal.

Measure of biological effect of radiation (dose). Now superseded by the sievert (Sv): 1 Sv = 100 rems.

The rem is a unit used to derive a quantity called equivalent dose. This relates the absorbed dose in human tissue to the effective biological damage of the radiation. Not all radiation has the same biological effect, even for the same amount of absorbed dose. Equivalent dose is often expressed in terms of thousandths of a rem, or mrem. To determin [..]

A unit in the traditional system of units that measures the effects of ionizing radiation on humans.

Rapid eye movement

The old unit for dose equivalent. 1 rem = 0.01 Sv

This is short for rapid eye movement, the stage of sleep when your eyes move back and forth under your closed eyelids and you have dreams. G'night!

is the number of remaining spaces available for students to enroll in a specific class.

Abbreviation for roentgen equivalent man, a measure of radiation received by an individual. A dose of 100 rem will cause severe illness; 500 rem more is considered fatal.

The unit of dose equivalent from ionizing radiation to the total body or any internal organ or organ system. A millirem (mrem)" is 1/1000 of a rem.

Receiver Equipment Monitor within the Downlink Channel (DC) of the Downlink Tracking & Telemetry subsystem (DTT).

a unit used in radiation protection to measure the amount of damage to human tissue from a dose of ionizing radiation. The amount of ionizing radiation required to produce the same biological effect as one rad of high-penetration x-rays. An average American receives about 0.370 rems of radiation per year.

REM (Real Estate Magazine) is a monthly Canadian real estate trade journal. It is commonly referred to by its abbreviated title, "REM" (pronounced as one word, /ˈrɛm/).

In radiation, an international unit of X-ray or gamma-ray radiation adjusted for the atomic makeup of the human body.

Former unit of dose equivalent, symbol: rem. For radiation protection purposes, the radiation dose was frequently indicated in millirem (mrem). 1 rem = 1 000 mrem. The new unit of the dose equivalent [..]

Rapid eye movement. The phase of sleep associated with dreaming and distinguished from the other stages of sleep by rapid movement of the eyes.

Abbreviation for rapid eye movement, which occurs during a period of sleep characterized by intense brain activity, often associated with dreams.
