Leakage Radiation: Complies to 601-1-3 IEC Section 29.204 “Leakage
Radiation”. Maximum continuous power input equals
1,400 heat units per min. (HU/Min.) tube is the limiting
factor. HU/Min. = (kV) x (mA) x (1.4) x (Exp. Time
(sec) / 60)
1,400 HU/Min. = 65 kV x 0.27mA x 1.4 x 60 sec.
X-Ray Coverage: The insert target angle is 12.5°
