Mechanism of regulation of ionizing radiation automatic d

Technical requirements for the device are as follows:
 the dimensional length of the device L is not more than 200 mm;
 the diameter of the device D is not more than 330 mm;
 the diameter of the covered section d = 200 mm;
 the diaphragm in extreme positions must be fixed;
 the temperature range of operation from minus 50 to plus 50 ° C;
The mechanism must ensure the workability:
• after the impact of overload, acting in the axis direction nx = ny = nz = 100g;
• under the impact of the load nx ≤ ny ≤ nz ≤ 5g, acting in any direction
