The symbol R means roentgen
the acronym rad means radiation absorbed dose
the roentgen (R) exposure is measured in air
the symbol mR means milliroentgen
one roentgen or 1 R is equal to 1000 milliroentgen
the acronym rem stands for roentgen equivalent man
the initialism QF stands for quality factor
the quality factor for X-rays and gamma rays is 1
the quality factor for alpha (ray) particles is 20
activity of radioactive material is measured in curies
Becquerels and curies are units of measurement of decay rate
atoms that have excess energy and are unstable are radioactive
known as
elementary particle units with a negative electrical electrons
