“…The phone was rotated in various angle with the acquisition time of 3 min for every angle. It concludes from this research that Radioactivity Counter can measured radiation without any additional hardware at the dose rates higher than 10 μGy/h [23]. The relation between cpm and dose rate was confirmed to be linear due to previous research [20], [21], [23].…”

Radiation detection method has been developed through years. It started from the complex module tools to simple handheld instrument. Recently, the more ease method has been developed with the help of smartphone application. To detect radiation using smartphone usually required the external tools connected to the phone as detector, but there is one application that did not. This application only required complementary metal-oxide semiconductor (CMOS) part of camera. The application is a game changer in radiation protection because nowadays smartphone is in everyone’s pocket. The application needs to be tested to ensure its effectiveness to detect radiation. The application has been tested by the previous research and it is effective to detect radiation. In this research, CMOS will be tested to detect radiation leakage of x-ray tube. The aim of this research is to find the effectiveness of CMOS in smartphone for radiation leakage detection of x-ray tube. The finding will help the radiation worker detect leakage radiation of x-ray tube using smartphone in case of the absences of surveymeter in the facility. The radiation from x-ray machine were detected and measured three times by Iphone 6s, Xs, and 11 using RadioactivityCounter. To ensure there was a leakage, surveymeter is used as a comparative modul. The data obtained from the experiment was analyzed using t-test. The result show that percentage error of Iphone 6s, Xs, and 11 Consecutively were 93.4%, 98.2%, and 98.9%. which mean CMOS in these said phone could detect and measured radiation ineffectively. This due to the low leaked intensity x-ray that came from x-ray machine. From the T-test anaysis found that only Iphone 11 had linear comparison to surveymeter

“…In addition to the large thematic groups described above, one can find a number of publications in which 3D models of various objects were made using images taken from a phone [ 80 , 81 , 82 , 83 , 84 , 85 , 86 , 87 , 88 , 89 , 90 , 91 , 92 , 93 ]. Smartphones were also used in radioactivity detection [ 94 ] or in forensic science [ 95 , 96 ]. It is worth mentioning that despite the increasingly frequent use of smartphone cameras for 3D modeling, it is very rare for the process to include camera calibration.…”

Recently, the term smartphone photogrammetry gained popularity. This suggests that photogrammetry may become a simple measurement tool by virtually every smartphone user. The research was undertaken to clarify whether it is appropriate to use the Structure from Motion—Multi Stereo View (SfM-MVS) procedure with self-calibration as it is done in Uncrewed Aerial Vehicle photogrammetry. First, the geometric stability of smartphone cameras was tested. Fourteen smartphones were calibrated on the checkerboard test field. The process was repeated multiple times. These observations were found: (1) most smartphone cameras have lower stability of the internal orientation parameters than a Digital Single-Lens Reflex (DSLR) camera, and (2) the principal distance and position of the principal point are constantly changing. Then, based on images from two selected smartphones, 3D models of a small sculpture were developed. The SfM-MVS method was used, with self-calibration and pre-calibration variants. By comparing the resultant models with the reference DSLR-created model it was shown that introducing calibration obtained in the test field instead of self-calibration improves the geometry of 3D models. In particular, deformations of local concavities and convexities decreased. In conclusion, there is real potential in smartphone photogrammetry, but it also has its limits.

“…To ensure safety under extremely high radiation conditions, a practical and easy-to-access monitoring system is needed. Johary et al (2021) described the use of sophisticated image sensors in today’s ubiquitous mobile phones that can detect both ionizing radiation and visible light. Smartphone cameras use a sensor called a CMOS (complementary metal oxide semiconductor) to capture images.…”

“…The Roland-Dieter Klein radioactivity counter is available for download in the Apple App Store. The smartphone CMOS sensor is very sensitive to radiation exposure as low as 10 μGy/h ( Johary et al, 2021 ). Similar CMOS sensors might be adapted for in-flight applications that offer relatively simple, inexpensive, and rapid deployment in space.…”

The space race is entering a new era of exploration, in which the number of robotic and human missions to various places in our solar system is rapidly increasing. Despite the recent advances in propulsion and life support technologies, there is a growing need to perform analytical measurements and laboratory experiments across diverse domains of science, while keeping low payload requirements. In this context, lab-on-a-chip nanobiosensors appear to be an emerging technology capable of revolutionizing space exploration, given their low footprint, high accuracy, and low payload requirements. To date, only some approaches for monitoring astronaut health in spacecraft environments have been reported. Although non-invasive molecular diagnostics, like lab-on-a-chip technology, are expected to improve the quality of long-term space missions, their application to monitor microbiological and environmental variables is rarely reported, even for analogous extreme environments on Earth. The possibility of evaluating the occurrence of unknown or unexpected species, identifying redox gradients relevant to microbial metabolism, or testing for specific possible biosignatures, will play a key role in the future of space microbiology. In this review, we will examine the current and potential roles of lab-on-a-chip technology in space exploration and in extreme environment investigation, reporting what has been tested so far, and clarifying the direction toward which the newly developed technologies of portable lab-on-a-chip sensors are heading for exploration in extreme environments and in space.
