a review on the book suicide and suicide prevention from a global perspective

background and objectives: due to the increasing use of ionizing radiation, this study aimed to investigate the radiation dose of students during their hospital internship course.materials and methods: in this descriptive study, the radiation dose received by radiology students during their hospital internship course at imam khomeini medical center in 2023 was investigated using a packet dosimeter. a total of 182 patients were radiographed with 363 exposures using different technical factors. the background radiation dose rate was measured using a geiger dosimeter. the radiation dose limit for each training session and the annual radiation exposure of students were calculated. a one-sample t-test was used to analyze the data.results: the average cumulative effective dose for students in each training session was 0.021 msv, and the annual radiation exposure was calculated to be 1.05 msv, which is below the dose threshold for radiation workers.conclusion: the dose received by the students is within the annual threshold of exposure for the general public. however, it is necessary for them to use a personal dosimeter device like other radiation workers.key words: radiography, internship, students, radiation dosimetryfunding: this study was funded by mazandaran university of medical sciences. conflict of interest: none declared. ethical considerations: the ethics committee of mazandaran university of medical sciences approved the study (ir.mazums.rec.1402.460). authors’ contributions: -conceptualization: gholamreza fallahmohammadi-methodology: gholamreza fallahmohammadi-data collection: amir saemian, mobina darbayar -formal analysis: gholamreza fallahmohammadi -supervision: gholamreza fallahmohammadi- project administration: gholamreza fallahmohammadi- writing – original draft: gholamreza fallahmohammadi, amir saemian, mobina darbayar - writing – review & editing: gholamreza fallahmohammadi
