  • Items that should get permits and approval
    Article 53 of the Nuclear Safety Act

Those who will produce, sell and use the radioactive isotopes or radiation generators or who will move and use them should get the approval from the Nuclear Safety and Security Commission according to the Presidential decree.
When any change to the approved work needs to be made, the same procedure will be applied (excluding the items that need to be reported and are to be exempted).

Classification Items that should be reported
Radioactive isotopes Sealed radioactive isotopes that do not exceed the standard usage or quantities of the following items,and do not have the risk of being damaged while being used or moved, and have the radiation mark indicated on the outside surface of the container or the device.

1. Usage
A. For X-ray fluorescent analysis
B. For X-ray diffraction analysis
C. Electron capture during the gas chromatography
D. Other items that are selected and notified by the Nuclear Safety and Security Commission

2. Quantities
A. If the radioactive isotopes are included in the calibration equipment, the radiation isotopes' quantity should be lower than 40MBq. While the equipment is being used, the surfaced dosage rate should be lower than 500μSv/h. While not being used, the rate should be lower than 1μSv/h.
B. If the radioactive isotopes are included in other containers or devices rather than the calibration equipment, the radioactive isotopes' quantity should be lower than what is stipulated by the Minister of the Ministry of Education, Science and Technology and the surfaced dosage rate should be lower than 10μSv/h and the containers or the devices should be capable of preventing any contact with the included radioactive materials.
Radiation generators Radiation generators that do not exceed the standard usage or quantities of the following items.

1. Usage
A. For X-ray fluorescent analysis
B. For X-ray diffraction analysis
C. For accelerated ion implantation
D. For searching through luggage
E. Self-shielded radiation generators with the maximum voltage lower than 170kV for the accelerated tube and with the surfaced dosage rate lower than 10μSv/h

2. Capacity
Self-shielded radiation generators with the maximum voltage lower than 170kV for the accelerated tubeand with the surfaced dosage rate lower than 10μSv/h
