Radiation Safety Guidelines Flashcards
1
Q
ICRP/NCRP risk increase for fatal cancer for workers
A
0.04 Sv
2
Q
ICRP/NCRP risk increase for fatal cancer for severe genetic effects
A
0.08 Sv
3
Q
NCRP rationale for lifetime fatality rate
A
0.7 Sv/lifetime
4
Q
ICRP rationale for tolerable fatal accident rates
A
1.0 Sv/lifetime
5
Q
Dose and Dose Rate Effectiveness Factor (DDREF)
A
ratio between slopes of low and high dose linear approximations
Can be used to estimate low rate risk from high rate data (high dose rate / DDREF)
6
Q
Partial body irradiation meaning
A
Partial doses to irradiated tissue add up to 100% if multiplied by tissue specific weighting factors
7
Q
Effective Dose Equivalent
A
H(E) = SUM (tissue weighting factor x Dose)
8
Q
___Joules per 1 MeV
A
1.6x10^-13 joules per 1 MeV
9
Q
Units of a Gy
A
Joule/kilogram
