“…According to [41], humans are exposed to radiation doses as high as 82% from cosmic and terrestrial sources, the inhalation of radioactive gas radon and its decay product inside any building, which all occur naturally. Furthermore, the ingestion of Potassium-40 in food can also lead to exposure [42,43]. Thus, radiation exposure needs to be measured whether the radiation originates from background radiation or any other nuclear activity, for safety purposes.…”

“…For occupational exposure, the radiation personnel working in nuclear facilities are highly likely to be exposed to radiological hazards. The NCRP suggested an annual effective dose of 50 mSv, and the ICRP recommended 20 mSv, averaged over 5 years with a dosage of no more than 50 mSv in any one year [43] while the AELB suggested a 20 mSv annual effective dose in a calendar year [44]. Being exposed to radiation for too long can be biologically harmful.…”

As nuclear technology evolves, and continues to be used in various fields since its discovery less than a century ago, radiation safety has become a major concern to humans and the environment. Radiation monitoring plays a significant role in preventive radiological nuclear detection in nuclear facilities, hospitals, or in any activities associated with radioactive materials by acting as a tool to measure the risk of being exposed to radiation while reaping its benefit. Apart from in occupational settings, radiation monitoring is required in emergency responses to radiation incidents as well as outdoor radiation zones. Several radiation sensors have been developed, ranging from as simple as a Geiger-Muller counter to bulkier radiation systems such as the High Purity Germanium detector, with different functionality for use in different settings, but the inability to provide real-time data makes radiation monitoring activities less effective. The deployment of manned vehicles equipped with these radiation sensors reduces the scope of radiation monitoring operations significantly, but the safety of radiation monitoring operators is still compromised. Recently, the Internet of Things (IoT) technology has been introduced to the world and offered solutions to these limitations. This review elucidates a systematic understanding of the fundamental usage of the Internet of Drones for radiation monitoring purposes. The extension of essential functional blocks in IoT can be expanded across radiation monitoring industries, presenting several emerging research opportunities and challenges. This article offers a comprehensive review of the evolutionary application of IoT technology in nuclear and radiation monitoring. Finally, the security of the nuclear industry is discussed.

“…Background radiation is present in all regions of the Earth. These types of radiation are the main source of human exposure and other living organisms from natural resources that permanently affect the dose received by humans and depend on the concentration of natural radioactive elements existing in the Earth's crust with different amounts (3)(4). The amount of the received dose from background gamma radiation can vary depending on latitude and longitude, and therefore, the intensity of biological effects can be different in different places (5)(6).…”

Introduction: Measurement of background gamma radiation in the human living environment, including hospitals, can provide useful information for epidemiological studies and authority bodies to consider appropriate strategies to reduce the exposure of these resources. Therefore, this study aimed to evaluate the background gamma radiation in surgical and other hospital wards, as well as indoors and outdoors of Valiasr, Razi, and Imam Reza hospitals in Birjand, Iran. Methods: Measurement of background gamma was performed according to the protocols of the International Commission on Radiation Protection by X5CPLUS survey meter. This study was conducted in Valiasr, Razi, and Imam Reza hospitals, South Khorasan province, Birjand, Iran, using a Geiger- Müller dosimeter in nano Sieverts per hour (nSv/h). Measurements were taken in the general sections and five stations outside the buildings (18 stations in total), and at each station, for half an hour and every minute, the readings were recorded at a distance of one meter from the ground. The average readings as dose background gamma were reported at the measured stations. Results: In the present study, among three evaluated hospitals, the maximum values in Razi, Imam Reza, and Valiasr hospitals were related to the urology department (62.04±13), orthopedic unit (94.66±20), and ENT department (60.7±19), respectively. On the other hand, the maximum outdoor dose values in Razi, Valiasr, and Imam Reza hospitals were in the southwest (62.5±12), southeast (57.9±13), and northwest (57±14), respectively. Furthermore, the minimum observed background radiation values in Valiasr, Razi, and Imam Reza hospitals were related to the emergency department (47.3±17), neurology department (51.86±17), and southwest point (53.9±19), respectively. Conclusion: The results of this study show that none of the hospital units nor outdoors in these hospitals can be introduced as a point where the amount of background radiation has an important concern.
