Maximum permissible

Various studies on the effects of X-ray radiation have provided the foundation for establishing maximum permissible dose of X-radiation. The results of these studies used by the National Council on Radiation Protection and the International Comittee on Radiation Protection to develop recommendat ions for the maximum permissible does (MPD). The I.C.R.P. recommendations can be interpreted to say that the maximum permissible dose (MPD) to the most critical organs, accumulated at any by the number of age, shall not exceed 5 x 10 -2Sv (5 rems} multiplied years beyond age 18 and the dose in any 13 consecutive weeks shall not for those involved in radiological Thus, exceed 3 x 10s2Sv (3 rems}. works, accumulation MPD equals 5(N-18) x 10W2Sv {5(N-18) rems), where N For the hands, forearms, and is greater than 18. is the age in years the MPD is set at 75 x 10T2Sv and ankles of radiologists, feet, (75 2.2.3

Perform tube voltage adjustments for each tube current setting. Although tube voltatges, 30 kV, 40 kV, 60 kV, 90 kV, 120 kV and 150 kV, are to be adjusted in principle, any voltage between tube voltage sections (see Note 2) can be adjusted. If the tube current value differs greatly from the value preset by means of the operation panel, the tube voltage cannot be adjusted. In such cases, therefore, the tube current adjustment should also be made along with the tube voltage adjustment. The delay time of the tube voltmeter should be 20 msec.

TEST METHOD OF AUTOMATIC EXPOSURE MINIMUM EXPOSURE TIME
Objective When the X-ray tube potential is equal to or greater than 50kV, the minimum time for field emission equipment rated for pulsed operation shall exposure less than a time interval equivalent to two pulses, and the be equal to or time for all other equipment shall be equal to or less minimum exposure than l/60 second or a time interval required to deliver SmAs, whichever is greater (See 102.31(a)(3)(ii)).
