“…Geiger-Müller (GM) counters are among the oldest radiation detectors available and remain useful in field-deployed nuclear industrial archaeology as the first line of intervention on site. GM counters can be fitted with probes sensitive to alpha [37], beta [38], gamma [39][40][41], positron [42], or a combination of those ionising radiation types [43]. GM counters have several advantages in comparison to more sophisticated scintillators or semiconductor detectors that can perform gamma energy spectrometry: they are lowcost [44], [45] (p. 103), can be tuned to different radiation types easily by fitting filters, and produce digital pulses that are processed electronically in a straightforward manner [46,47].…”

The legacy of the early days of the Atomic Age consists of many problematic sites worldwide, including radioactive waste dumps, uranium mines, spent fuel reprocessing plants, and defunct processing and enrichment plants. Although nature quickly reclaims abandoned sites, any remaining radioisotopes can pose a threat for millennia to come, long after the benefits gained from nuclear technology have faded. The field of nuclear industrial archaeology specialises in finding and characterising these sites to support local communities and site owners. Where maps and building plans have been lost, nuclear archaeologists deploy state-of-the-art analysis techniques on the ground to unravel the current state of legacy sites, and quantify the remaining radioactive inventories to the standard required by the nation the site is located within. The objectives of nuclear industrial archaeology are varied and site dependent. Whether the objective is to puzzle the forgotten history of activity back together or safeguard and recover dangerous radioactive materials, nuclear industrial archaeology adapts radioanalytical laboratory and site-surveying techniques in order to understand the site and allow scientists to communicate this information to support remediation efforts. This paper discusses current methodologies alongside a case study.

“…The Geiger-Muller counter cannot distinguish the energy of the incident particles based on the pulse size for selective energy counting since a low energetic particle can create an avalanche across the entire chamber [15]. To detect the presence of charged particles, neutrons, and photons, the Geiger-Muller counter is a trustworthy detector [16].…”

This paper provides a review of radiation detectors to measure the ionizing radiation like gamma-ray, X-ray, high energy UV-ray and heavy ions, etc. It is essential to know about the radiation source and its effects for several applications such as aviation, medical, high energy physics experiments and space missions. In the last few decades, numerous detectors with different manufacturing technologies have been reported. Semiconductor devices such as diodes, metal-oxide-semiconductor field-effect transistors (MOSFETs) and solid-state photomultipliers (SSPMs), etc., have been made and widely used to measure different kind of radiation. This article goes through the evolution of radiation detectors design using various technologies and summarizes the features with emphasis on their underlying principles and applications.

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.
