Abstract

Nerazorna metoda radiografije, koja se sve više koristi u industriji za ispitivanje metalnih materijala donosi brojne prednosti, ali istovremeno izlaže osoblje i radnu okolinu opasnosti od zračenja. Upravo zbog toga, sigurnost pri primjeni ove metode je iznimno važna tema. Cilj završnog rada je pružiti dublji uvid u opasnosti i rizike od zračenja pri ispitivanju metalnih materijala nerazornom metodom radiografije, kroz konkretni primjer ispitivanja metalne cijevi u tvrtki STSI d.o.o. Prikazane su i provedene mjere predostrožnosti koje treba poduzeti kako bi se osigurala sigurnost osoblja i radne okoline. Nepravilna primjena ili nedostatak sigurnosnih mjera mogu dovesti do ozbiljnih posljedica, uključujući ozračenje osoblja i štetne utjecaje na okolinu. Stoga, osiguranje sigurnosti tijekom ispitivanja metodom radiografije postaje ključno. Pravilna obuka osoblja o sigurnosnim postupcima i korištenju zaštitne opreme poput dozimetara provedena je u ovom radu pri ispitivanju nerazornom metodom radiografije. Važnost održavanja sigurnosnih standarda u radnom okruženju, uključujući označavanje radioloških područja, ograničavanje pristupa neautoriziranim osobama i pravilno odlaganje radioaktivnog otpada utvrđeno je u radu kroz ispitivanje metalne cijevi nerazornom metodom radiografije. U radu je naglašena važnost sigurnosti pri primjeni metode radiografije u industrijskom ispitivanju metalnih materijala. Uz sigurnost osoblja pri ispitivanju metodom radiografije provedeno je ispitivanje kvalitete zavara na metalnoj cijevi pri čemu je utvrđeno je da ne pokazuje nikakve nedostatke. Također su utvrđene potencijalne opasnosti od zračenja prije, za vrijeme i nakon provođenja radiografskih ispitivanja pri čemu je određena obavezna zaštitna oprema i postupci.

Abstract (english)

The non-destructive method of radiography, which is increasingly being used in the industry for testing metallic materials, brings numerous advantages but at the same time exposes personnel and the working environment to radiation hazards. Due to this, safety in the application of this method is an extremely important topic. The aim of paper is to provide a deeper insight into the dangers and risks of radiation during the testing of metal materials using the non-destructive method of radiography, through a specific example of testing a metal pipe at STSI Ltd. The precautionary measures that need to be taken to ensure the safety of personnel and the working environment are presented and performed. Improper application or lack of safety measures can lead to serious consequences, including personnel irradiation and adverse effects on the environment. Therefore, ensuring safety during radiographic testing becomes crucial. Proper staff training on safety procedures and the use of protective equipment such as dosimeters was carried out in this paper during examination by the non-destructive method of radiography. The importance of maintain safety standards in the work environment, including the marking of radiological areas, restricting access to unauthorized individuals, and proper disposal of radioactive waste is established in the paper through the examination of a metal pipe by the non- destructive method of radiography. In the paper, the importance of safety in the application of radiographic methods in industrial testing of metallic materials is emphasized. In addition to the safety of the personnel during the examination by radiography, a test of the weld quality on the metal pipe was carried out. It was determined that it did not show any defects. Potential hazards from radiation before, during and after radiographic tests were also determined, where protective equipment and procedures are provided.
