Formulae (4) Flashcards
1
Q
Dose Rate/Intensity Formula
A
A x Characteristic Intensity = Dose rate
A=Ci, Chi=R/h) (A=GBq, Chi=mSv/h
2
Q
Exposure Dose is measured through…
A
c/Kg (coulombs per Kilogram)
3
Q
Gray (Gy)
A
Unit of absorbed dose (the absorption of 1 joule of ionizing energy per Kilogram of matter)
4
Q
Radiation Absorbed Dose (rad)
A
Unit of absorbed dose
(the absorption of 100ergs of energy per gram of matter)
(1rad = 1R of gamma exposure )
5
Q
Units for absorbed dose and conversion
A
- Gray (Gy)
- Radiation Absorbed Dose (rad)
- 1J = 10⁷ ergs
- 1Kg = 1,000g
- 1 Gy = 100 rad
6
Q
Does Equivelent
A
Absorbed Dose x RBE = Equivalent Dose
- measured in roetegen equivalent to man (rem)
- Gy x RBE = Sv
- rad x RBE = rem
7
Q
Conversions for dose equivalent
A
- 1 Sv = 100 rem
- 1 mSv = 100 mrem
