Scheme: EC = Electron Capture IT = Isomeric Transition
Notes:
1.
Isotope:
A/B implies that B is in equilibrium with A.
2.
Half life
: s = seconds, m = minutes, d = days, y = years.
3.
Scheme:
E = electron capture, B – beta decay, IT = isomeric transition, A = alpha decay.
4.
Cal Value:
Atomlab dose calibrator dial setting to calibrate for corresponding isotope
5.
Notes:
*H(r) = Half life ratio of daughter over parent, implies daughter is ignored.
** Bremsstrahlung includes low energy photons from electron interaction in saline.
Isotope should be measured in plastic syringe or vial or thin wall glass ampule unless otherwise
stated above.
Calculated or Measured:
C: Calculated with corrected Monte Carlo.
B: Beta MC, response strongly dependent upon measurement geometry; best if Cal Value is
determined using the actual measurement with clinical geometry.
M: Confidence value of a measurement made using the listed dial value.
