る。 Note that FIG. 1 is an example in which two linear accelerators 1 and 1a are arranged at opposite positions with respect to the object 4 to be irradiated. The linear accelerators 1 and 1a are fixed, and when the object 4 to be irradiated is conveyed by the conveyor 5,
If an object 4 to be irradiated enters the irradiation field 3 of the first linear accelerator 1, it will be irradiated with radiation. At this time, the conveyor 5 may move continuously, or the object 4 to be irradiated may be completely within the irradiation field 3 for a certain period of time
You may also irradiate with a line. Similarly, the second linear accelerator 1a irradiates the object 4 with X-rays from the direction opposite to that of the first linear accelerator. Linear accelerators 1, 1a,...
If three or more units are installed, this operation will be repeated one after another.

で、線量が最大になり、それより深くなると線量
はだんだん小さくなる。 FIG. 2 shows an X-ray deep dose curve 6 when there is only one linear accelerator 1. This represents the dose intensity in the irradiated material. At a certain depth below the surface, the dose is maximum, and as you go deeper, the dose gradually decreases.

線７のようになる。 Figure 3 shows the linear accelerators 1 and 1a as in Figure 1.
It is a deep dose curve diagram when two units are arranged and X-rays are irradiated. In this case, since X-rays are irradiated from both the front and back of the irradiated object 4, the two deep dose curves 6 are superimposed and synthesized to form a deep dose curve 7.
以上のように、直線加速器１を２台以上（偶数

得られ、むらのない均一な処理ができる。なお、
線量を多くし、処理スピードを上げるためには３
台配設するなど奇数台でもよい。 As described above, by using two or more linear accelerators 1 (an even number), a uniform dose distribution can be obtained in the irradiated object 4, and uniform treatment without unevenness can be achieved. In addition,
3 to increase the dose and speed up the processing
An odd number of units may be used.
また、被対照物４が簿型又は小型の場合には、
直線加速器１をベルトコンベア５に対して片側に
並列してＸ線を照射しても良い。 In addition, if the object to be compared 4 is book-shaped or small,
The linear accelerator 1 may be placed in parallel on one side of the belt conveyor 5 to irradiate X-rays.
さらに、ベルトコンベア５の上方から下方へ又

あるいは下方から上方に向けて照射してもよい。 Furthermore, the irradiation may be performed from above to below the belt conveyor 5 or from diagonal directions,
Alternatively, the light may be irradiated from below to above.
