What are rems?
The Rem used to be used in Health Physics to measure radiation dose, it is an acronym for Rontgen Equivalent Man.(The methodology allows for the different effects of different types of radiation). The unit now used is the Sievert (Sv), 1 Sievert = 100 Rem. This is a large unit, so millisieverts are used for practical personnel radiation measures, so 1 millisievert = 100 millirem. Recommended radiation levels for nuclear workers are set by the ICRP (International Committee for Radiation Protection). These used to be set at 5 Rem/year (50 milliSv) but now the level is 20 milliSv/year ie 2 Rem/year. The use of Rem and millirem has been discontinued in the nuclear industry in favour of Sieverts and millisieverts. However as someone with nuclear experience going back to 1958 I find it difficult to think in Sieverts. For example I know that 500 Rem will kill roughly 1/2 the people exposed to it within a month, now I have to change that to 5 Sieverts. Fortunately that level of exposure has only happened once (at Chernobyl).
What is the lethal radiation limit for humans?
1000 Rem or 10 Sieverts will almost certainly kill within a few weeks. 500 Rem or 5 Sieverts will kill about 1/2 those receiving it.
What are the units of radiation doses?
Sieverts and milliSieverts are used now. They replaced the old rem and millirem. There is a factor 100 difference, so 1 Sievert = 100 Rem. The current limit for nuclear industry employees is 20 milliSv/year, though the actual average level in the US is about 2.4 milliSv.
A unit of energy is the unit of what?
... is called power. The SI unit for energy is the joule; the SI unit for power is joule/second = watt.
Is newtons a unit of pressure?
No. A Newton is a unit of force, while pressure is force per unit area. The standard unit of pressure is a Pascal, which is also a derived SI unit.
Which unit of radiation dose rem or rad is most useful for describing the effect of radiation on living tissue?
rem
Which unit of radiation dose- rem or rad -is most useful for describing the effect of radiation on living tissue?
rem
What wire goes to the rem on a amp?
There will be a wire on the back of your head unit that turns the amp on. It will be marked something like "rem" "remote" or "amp." If not, consult your head unit manual.
What is a millirem?
Unit used to measure radiation dosage (1/1000 of a rem)
What unit are use to measure radiation?
Roentgen (or Becquerel)Rad (or Grey)Rem (or Sievart)Depending on what you want to measure
REM rebound involves the?
REM rebound involves the tendency for REM sleep to increase following REM sleep deprivation.
The standard unit of radiation related to biologic hazard is known as the?
The standard unit of radiation related to biological hazard is known as sievert denoted by Sv. The smaller unit for the same is called rem (100 rem is 1 Sv). The difference between the unit of absorbed dose(Gray / rad) and Sv is that sievert also takes into account the biological effectiveness of the different types of radiation
What is plural of rem?
The plural form of rem is rem.Ex: I have a lifetime dose of 3 rem.
What is the difference between rad and rem?
The Rad is a unit of ionizing radiation, measuring its energy distribution in air. A Rontgen is similar, but it measures the energy absorbed by an object. A REM is a Rontgen Equivalent Man, so it measures the energy absorbed by a human being.
