12.3.2. X-Ray Source Assembly
2.55 mm Al @50KV with LOHMANN tube
Maximum continuous heat dissipation rate
Tube assembly dimension (length×Width×Height)
Maximum symmetrical radiation field on the X-axis
100cm from the spot:
Fluoro: 235 mm (diagonal)
Film: 240mm (diameter)
Max. uninterrupted fluoro time (70KV/4.3mA, 8PPS)
Dose rate is less than 1.0mGy/h, averaged
over any area of 100 cm
2
of which no principal
linear dimension exceeds 20 cm at 1 m from
the focal spot under conditions of loading.
Leakage radiation test condition
Location of the focal spot and the reference axis
The reference axis is from the center of the
focal spot to the center of the image
intensifier. Focal spot’s tolerances on the
reference axis is zero.
