Machines that emit radioactive X-rays include: X-ray machines for chest X-rays in hospitals, medical CT machines, X-ray flaw detectors commonly used in industry, dental X-ray machines in dental clinics, and aircraft and train luggage security inspection equipment . . . . . . . X-rays are rays produced by an X-ray tube under high pressure.
γ rays are generally rays produced by the decay process of radioactive isotopes. Different isotopes (the same isotope) emit γ rays during the decay process, and may also emit α, β or neutron rays. Such as gamma flaw detectors, nuclear material level meters, nuclear scales, nuclear thickness gauges, and irradiation processing in our industry. . . . . . .
These things cannot be bought and sold casually. They must apply, register and file with the environmental protection department before they can be bought, sold and used
