Abstract
The results of measurements of the content of radioactive elements in ore samples from the Tomtor integral rare metal deposit are considered with the aim of safe use of ore with rare earth elements as a modifier of the weld pool during the processes of manual arc welding and fusing. It was revealed using a semiconductor gamma spectrometer that a significantly larger proportion of ionizing radiation activity is represented by the thorium-232 family. It is noted that natural concentrate is added to the composition of welding materials in very small quantities, and during welding operations in the room next to the welder, the values of the exposure dose rate will correspond to the initial radiation background in the room, therefore, both the welder and those people who will be in contact with the welded materials will not receive additional radiation dose to the natural background. It was concluded that the process of manufacturing the welding materials, welding, fusing and the use of welded structures are completely safe in terms of radiation.
