Radiological procedures are indispensable in modern medicine, but at the same time, the issue of radiation exposure to medical workers remains serious. In particular, appropriate feedback on radiation exposure levels to radiation workers is essential for improving personal protection awareness and occupational radiation exposure management. In Japan, radiation exposure level notifications are mainly distributed on paper, which poses issues such as loss and complicated confirmation procedures. In contrast, email notifications are convenient and immediate, but whether the recipient has read the content is unclear. Therefore, this study aims to implement radiation exposure level notification via email for radiation workers and quantitatively evaluate the confirmation of these email opening statuses. The target was set as radiation workers in medical institutions. Every month, managers at medical institutions attached PDF notification forms listing the previous month's radiation exposure levels to emails sent to the relevant radiation workers. The system for sending emails had a feature that allowed administrators to track whether emails had been opened. The administrator recorded the opening status one week and one month after sending. This process was continued for six months, and the email opening rates were analysed one week and one month after sending. The opening rates were calculated as the percentage of radiation workers who opened the email one week and one month after it was sent. As a result of checking email opening rates over six months, the percentage of emails opened within one week of being sent ranged from 74.2% to 86.4%, and within one month, the rate ranged from 90.3% to 97.7%. The opening rates did not reach 100% in all months, and many people who did not open the emails were recognised throughout the six months. This study revealed the effectiveness and limitations of email notifications. This study showed that radiation exposure level notifications by email are highly immediate and reachable, but not all recipients necessarily confirm the contents. This result may be due to human factors such as differences in radiation protection awareness, delays in confirmation due to busy work schedules, and basic manners about checking received emails. In addition, unread radiation exposure level notifications indicate that the communication of essential information for occupational radiation exposure management is not being ensured, and a review of notification methods is required. Email notification of radiation exposure levels is an effective means of supplementing paper-based notifications. However, individual differences in the opening status suggested that the reliable transmission of essential information, such as radiation exposure levels, might not be sufficiently ensured. |
