What is radiation measured in?

Answer 1

The answer is Rads. Did you know that 1,000 Rads can kill a man, while some bugs can withstand 1,000,000 Rads!!!

noo its Becquerels or Curie, RADS is an old measurement or nuclear radioactivity of Alpha Beta and Gamma.

Actually all of this is true. There are lots of ways of measuring radiation depending an what it is about radiation you want to measure. This may help:

Radiation Measurements

Curie - Named after Mary Curie. This measurement is used to measure

how radioactive an object is and/or how much radiation it

produces.

Roentgen - How much radiation is present in the air of a specific environment

Rad/Rem - Measure of any type of ionizing radiation including Alpha, Beta,

Gamma and 'X'. It measures How much radiation is absorbed by an

object.

More on Rems and Rads

Rad stands for Radiation Absorbed Dose. 1 Rad is 100ergs (ergs is a measurement of energy)

Rem stands for Roentgen Equivalent Man. Used to describe and define the limits of people who are around radiation. (How much radiation they can take.) Rems can also be presented as millirems and rems per hour.

The Metric version of Rads and Rems is Gray and Sievent.

Gray is a precise measurement of the amount of energy the ionizing radiation gives to the tissue it passes through.

Sievent takes into account the types of radiation and gives a biological measurement of how dangerous the absorbed radiation is to the body.

Answer 2

Units of measurement for radioactivity and radiation doses. In SI units, the activity of a radioactive source is measured in becquerels (symbol Bq), where one becquerel is equal to one nuclear disintegration per second (an older unit is the curie). The exposure is measured in coulombs per kilogram (C kg-1); the amount of ionizing radiation (X-rays or gamma rays) that produces one coulomb of charge in one kilogram of dry air (replacing the roentgen). The absorbed dose of ionizing radiation is measured in grays (symbol Gy) where one gray is equal to one joule of energy being imparted to one kilogram of matter (the rad is the previously used unit). The dose equivalent, which is a measure of the effects of radiation on living organisms, is the absorbed dose multiplied by a suitable factor that depends upon the type of radiation. It is measured in sieverts (symbol Sv), where one sievert is a dose equivalent of one joule per kilogram (an older unit is the rem).

Answer 3

Radioactivity or the strength of radioactive source is measured in units of becquerel (Bq).

1 Bq = 1 event of radiation emission per second.

One becquerel is an extremely small amount of radioactivity. Commonly used multiples of the Bq unit are kBq (kilobecquerel), MBq (megabecquerel), and GBq (gigabecquerel).

1 kBq = 1000 Bq, 1 MBq = 1000 kBq, 1 GBq = 1000 MBq.

An old and still popular unit of measuring radioactivity is the curie (Ci).

1 Ci = 37 GBq = 37000 MBq.

One curie is a large amount of radioactivity. Commonly used subunits are mCi (millicurie), µCi (microcurie), nCi (nanocurie), and pCi (picocurie).

1 Ci = 1000 mCi; 1 mCi = 1000 µCi; 1 µCi = 1000 nCi; 1 nCi = 1000 pCi.

Another useful conversion formula is:

1 Bq = 27 pCi.

Becquerel (Bq) or Curie (Ci) is a measure of the rate (not energy) of radiation emission from a source.

Answer 4

For the effective dose of radiation the unit is sievert (Sv).
