Abstract

Background and Aim: Estimation of radon density  in underground centers is very important. Considering the use of high-energy medical accelerators, radiotherapy departments are usually located in underground floors. The aim of this study was to evaluate staff exposure to radon gas in these centers in Tehran in 2015-2016.
Materials and Methods: This is a descriptive,  cross-sectional survey. In radiotherapy centers of Tehran, 32 radon gas diffusion chamber detectors were installed for a period of 3 months. After collecting the detectors, radon gas concentrations were calculated. The annual effective dose of personnel was evaluated using staff’s working hours per week.  
Results: The minimum and maximum concentrations recorded in this study during one year were 22.14 and 398.52 Bq/m3, respectively, with an average of 87.01 ± 80.68 Bq/m3. Also, radiotherapy personnel’s annual effective dose was 0.34 ± 0.43 mSv per year with the minimum and maximum amounts of 0.02 and 2.35 mSv per year, respectively.
Conclusion: The results indicate that radon level in radiotherapy centers and also that the annual effective dose of personnel in these centers are permissible, and no special action is needed. However, if more attention is paid to certain factors such as air-conditioning, the amount of the gas can even be brought to less than this limit.

Abstract

Background and Aim: Today along with information technology development, telemedicine technology has expanded dramatically. Sinse telemedicine technology relies on data transmission, it is essential to pay attention to issues such as network security, confidentiality, and privacy of patients. Therefore, the aim of this study was to determine the importance of information security requirements in telemedicine networks based on managers and employees of the information technology unit of the University and teaching hospitals of Birjand city 
Materials and Methods: This descriptive cross-sectional study was conducted in year 2021. The research population was The managers and employees of the information technology unit of the university and teaching hospitals of Birjand city (40 people), who were surveyed by the census. The study tool was a researcher-made questionnaire that confirmed its validity by faculty members and experts, and its reliability was calculated with Cronbach’s alpha (0.83). After collecting the data, they were entered into the SPSS software and were analyzed using descriptive statistics.
Results: The results showed that the security requirement related to information transportation is more important than other requirements. Also in the field of human resources, providing detailed documentation and training guides for users of the systems was with an average of (4.47). In the medical diagnosis equipment field, telemedicine network systems are equipped with emergency power was with an average of (4.72). In the storage and access to information context, installing antiviruses and anti-malware on all systems was with an average of (4.75), and also in the field of information transfer, encryption of important and sensitive files and information was with an average of (4.69) were the most important security needs.
Conclusions: As the results showed, security requirements related to information transfer have more importance than other requirements; Initially, information security can be guaranteed by creating security policies, updating and monitoring their implementation, as well as training employees. However, in order to transfer sensitive medical information, encryption and qualification verification methods, secure information transfer protocols, virtual and private networks (VPN) and other new technologies can be used in this field. Of course, necessary preparations should be made to create appropriate technical infrastructure for the implementation of security policies in information transmission.
