“…Human health risk during space operations has been detected by NASA [24].Even though contributions to HZE particles to the dosimetry throughout the space atmosphere have been undertaken in multiple operations throughout the Apollo period [25], the spaceship [26][27], the station [28], and the ISS [29][30][31], the HZE particles add significantly the dosage exposure because of the strong LET, leading in important biochemical consequences. Men on the Moon Circular Stations would be subjected to substantially greater doses of ionizing radiation than crews on LEO flights.…”

The fast developments and ongoing demands in radiation dosimetry have piqued the attention of many software developers and physicists to create powerful tools to make their experiments more exact, less expensive, more focused, and with a wider range of possibilities. Many software toolkits, packages, and programs have been produced in recent years, with the majority of them available as open source, open access, or closed source. This study is mostly focused to present what are the Monte Carlo software developed over the years, their implementation in radiation treatment, radiation dosimetry, nuclear detector design for diagnostic imaging, radiation shielding design and radiation protection. Ten software toolkits are introduced, a table with main characteristics and information is presented in order to make someone entering the field of computational Physics with Monte Carlo, make a decision of which software to use for their experimental needs. The possibilities that this software can provide us with allow us to design anything from an X-Ray Tube to whole LINAC costly systems with readily changeable features. From basic x-ray and pair detectors to whole PET, SPECT, CT systems which can be evaluated, validated and configured in order to test new ideas. Calculating doses in patients allows us to quickly acquire, from dosimetry estimates with various sources and isotopes, in various materials, to actual radiation therapies such as Brachytherapy and Proton therapy. We can also manage and simulate Treatment Planning Systems with a variety of characteristics and develop a highly exact approach that actual patients will find useful and enlightening. Shielding is an important feature not only to protect people from radiation in places like nuclear power plants, nuclear medical imaging, and CT and X-Ray examination rooms, but also to prepare and safeguard humanity for interstellar travel and space station missions. This research looks at the computational software that has been available in many applications up to now, with an emphasis on Radiation Dosimetry and its relevance in today's environment.

“…Numerous space radiation dosimetry campaigns have been carried out in the pressurized module (PM) of the ISS (e.g., Ambrožová et al, 2011;Nagamatsu et al, 2013;Kodaira et al, 2013;Kroupa et al, 2015;Berger et al, 2016Berger et al, , 2017. The typical daily dose rate inside the ISS ranges from about 0.5 to 1 mSv (0.2 to 0.5 mGy) depending on the solar activity and orbital and shielding parameters of the module.…”

Radiation dosimetry was carried out at the exposure facility (EF) and the pressurized module (PM) of the Japanese Kibo module installed in the International Space Station as one study on environmental monitoring for the Tanpopo mission. Three exposure panels and three references including biological and organic samples and luminescence dosimeters were launched to obtain data for different exposure durations during 3 years from May 2015 to July 2018. The dosimeters were equipped with additional shielding materials (0.55, 2.95, and 6.23 g/cm 2 mass thickness). The relative dose variation, as a function of shielding mass thickness, was observed and compared with Monte Carlo simulations with respect to galactic cosmic rays (GCRs) and typical solar energetic particles (SEPs). The mean annual dose rates were D EF = 231 -5 mGy/year at the EF and D PM = 82 -1 mGy/ year at the PM during the 3 years. The PM is well shielded, and the GCR simulation indicated that the measured mean dose reduction ratio inside the module (D PM /D EF = 0.35) required *26 g/cm 2 additional shielding mass thickness. Observed points of the dose reduction tendency could be explained by the energy ranges of protons (10-100 MeV), where the protons passed through, or were absorbed in, the shielding materials of different mass thickness that surrounded dosimeters.

“…Detailed characterization and visualization of the energetic and mixed radiation field in space is valuable as well to assess single event effects in electronic equipment and health hazards to crews on manned missions. Besides conventional passive detectors 10) , the deployment of active real-time data acquisition and position-sensitive radiation detectors on board spacecraft would be highly advantageous for space radiation detection 9) and spacecraft radiation monitoring.…”

A customized lightweight and low-power radiation micro-tracker has been constructed for the microsatellite RISESAT (Rapid International Scientific Experiment Satellite) developed by Tohoku University for scientific experiments in space. The instrument is based on hybrid semiconductor pixel detector technology developed by the Medipix Collaboration. These Timepix detectors consist of an array of 256 × 256 (= 65 k) pixels with 55 m pitch distributed over area of 2 cm 2 . Each cell is connected to the corresponding pixel on the 300 m thick siliconsensor. Each pixel integrates electronics which enables counting of the number of particles, to measure the energy deposited or to register the time of interaction of ionizing particles per-pixel. Two independent detector layers operate as a radiation micro-telescope and provide high resolution and high sensitivity tracking and directional detection of energetic charged particles (electrons, muons, pions, protons, light ions up to heavy and relativistic ions). Also X-rays and even neutrons can be detected. The pixel detectors provide noiseless detection of single radiation quanta, measure their energy, position, direction of trajectory and time of interaction. Different types of particles and interactions can be identified and distinguished thanks to the detector's high spatial granularity.
