Prospect
Now more and more EB irradiators put into use than Gamma;
Some ways , EB more safety, cut off the power, no radiation;
But EB poor penetration than Gamma;
X-ray maybe OK, but need time;
In the short term, gamma is still dominant, but the long term, maybe EB or X-ray

44. Thank you! For more information: Exhibition Booth (SQHL)
