|||
== Activity of an isotope or material, 1 curie = 37 billion disintegrations per second. == |
|||
The Curie (Ci) is the inverse of Becquerel (Bq) |
|||
The Becqurel (Bq) is inverse of the Curie (Ci) |
|||
1 curie (Ci) = 37 gigabecquerel (GBq) |
|||
1 gigabecquerel (GBq)=27 millicurie (mCi) |
|||
== Radiation Absorbed Dose (rad); a dose of 1 rad means the absorption of 100 ergs of radiation energy per gram of material == |
|||
The rad (rad) is the inverse of the gray (Gy) |
|||
The gray (GY)is the inverse of the rad (rad) |
|||
1 rad (rad) = 10 milligray (mGy) |
|||
1 milligray (mGy) = 100 millirad (mrad) |
|||
'''A unit of exposure to ionizing radiation. Only used by well trained personel.''' |
|||
== The amount of gamma or x-rays required to produce ions carrying 1 electrostatic unit ef electrical charge (either positive or negative) in 1 cc of dry air under standard conditions. == |
|||
The roentgen (R) is the inverse of coulomb/kg (C/kg) |
|||
Coulomb/kg is the inverse of the roentgen (R) |
|||
1 roentgen (R) = 258 microcoulomb/kg (mC/kg) |
|||
1 millicoulomb/kg mC/kg = 3876 milliroentgen (mR) |
|||
== Roentgen Equivalent Man (rem) == |
|||
The rem (rem) is the inverse of the sievert (Sv) |
|||
The Sievert (Sv) is the inverse of the rem (rem) |
|||
1 rem (rem) = 10 millisievert (mSv) |
|||
1 millisievert (mSv) = 100 millirem (mrem) |
|||
== Counts Per Minute (CPM) == |
|||
Used for alpha particles, beta particles or mixed gamma/beta, gamma/alpha, alpha/beta actual counts per minute. |
|||
