Halide lead perovskites for Ionizing Radiation detection
Nature Communications, 2019Co-Authors: Haotong Wei, Jinsong HuangAbstract:Halide lead perovskites have attracted increasing attention in recent years for Ionizing Radiation detection due to their strong stopping power, defect-tolerance, large mobility-lifetime (μτ) product, tunable bandgap and simple single crystal growth from low-cost solution processes. In this review, we start with the requirement of material properties for high performance Ionizing Radiation detection based on direct detection mechanisms for applications in X-ray imaging and γ-ray energy spectroscopy. By comparing the performances of halide perovskites Radiation detectors with current state-of-the-art Ionizing Radiation detectors, we show the promising features and challenges of halide perovskites as promising Radiation detectors.Halide lead perovskites have emerged recently as possible candidates for high performance Radiation detectors besides efficient solar cells. Here Wei et al. review the recent progress on perovskite based Radiation detectors and suggest that they may compete with the conventional counterparts.

The similar effects of low-dose Ionizing Radiation and non-Ionizing Radiation from background environmental levels of exposure
The Environmentalist, 2012Co-Authors: Cindy SageAbstract:The meltdown and release of radioactivity (Ionizing Radiation) from four damaged nuclear reactors at the Fukushima Nuclear Facility in Japan in March 2011 continues to contaminate air and ocean water even 1 year later. Chronic exposure to low-dose Ionizing Radiation will occur over large populations well into the future. This has caused grave concern among researchers and the public over the very long period of time expected for decommissioning alone (current estimate from official sources is 30–40 years based on TEPCO in Mid-and long-term roadmap towards the decommissioning of Fukushima Daiichi nuclear power units 1–4, 2011 ) and the presumed adverse effects of chronic, low-dose Ionizing Radiation on children, adults and the environment. Ultimately, radioactive materials from Fukushima will circulate for many years, making health impacts a predictable concern for many generations (Yasunari et al. in PNAS 108(49):19530–19534, 2011 ). There is long-standing scientific evidence to suggest that low-dose Ionizing Radiation (LD-IR) and low-intensity non-Ionizing electromagnetic Radiation (LI-NIER) in the form of extremely low-frequency electromagnetic fields and radiofrequency Radiation (RFR) share similar biological effects. Public health implications are significant for reconstruction efforts to rebuild in post-Fukushima Japan. It is relevant to identify and reduce exposure pathways for chronic, low-dose Ionizing Radiation in post-Fukushima Japan given current scientific knowledge. Intentional planning, rather than conventional planning, is needed to reduce concomitant chronic low-intensity exposure to non-Ionizing Radiation. These are reasonably well-established risks to health in the scientific literature, as evidenced by their classification by World Health Organization International Agency for Research on Cancer as Possible Human Carcinogens. Reducing preventable, adverse health exposures in the newly rebuilt environment to both LD-IR and LI-NIER is an achievable goal for Japan. Recovery and reconstruction efforts in Japan to restore the communications and energy infrastructure, in particular, should pursue strategies for reduction and/or prevention of both kinds of exposures. The design life of buildings replaced today is probably 35–50 years into the future. Cumulative health risks may be somewhat mitigated if the double exposure (to both chronic low-dose IR from the Fukushima reactors and LI-NIER [EMF and RFR] in new buildings and infrastructure) can be dealt with effectively in early planning and design in Japan’s reconstruction.

the iqid camera an Ionizing Radiation quantum imaging detector
Nuclear Instruments & Methods in Physics Research Section A-accelerators Spectrometers Detectors and Associated Equipment, 2014Co-Authors: Stephanie J. Gregory, Erin S. Fuller, Harrison H. Barrett, Brian W Miller, Bradford H Barber, Lars R. FurenlidAbstract:Abstract We have developed and tested a novel, Ionizing-Radiation Quantum Imaging Detector (iQID). This scintillation-based detector was originally developed as a high-resolution gamma-ray imager, called BazookaSPECT, for use in single-photon emission computed tomography (SPECT). Recently, we have investigated the detectors response and imaging potential with other forms of Ionizing Radiation including alpha, neutron, beta, and fission fragment particles. The detector’s response to a broad range of Ionizing Radiation has prompted its new title. The principle operation of the iQID camera involves coupling a scintillator to an image intensifier. The scintillation light generated particle interactions is optically amplified by the intensifier and then re-imaged onto a CCD/CMOS camera sensor. The intensifier provides sufficient optical gain that practically any CCD/CMOS camera can be used to image Ionizing Radiation. Individual particles are identified and their spatial position (to sub-pixel accuracy) and energy are estimated on an event-by-event basis in real time using image analysis algorithms on high-performance graphics processing hardware. Distinguishing features of the iQID camera include portability, large active areas, high sensitivity, and high spatial resolution (tens of microns). Although modest, iQID has energy resolution that is sufficient to discrimate between particles. Additionally, spatial features of individual events can be used formore » particle discrimination. An important iQID imaging application that has recently been developed is single-particle, real-time digital autoradiography. We present the latest results and discuss potential applications.« less
