“…3). A protective curtain of 6.3 g/cm 2 (total mass 67 kg) was installed along the outer wall of the starboard crew cabin in the Russian Service Module of the ISS (Kodaira et al, 2014). A dose equivalent reduction around 37% was measured on the ISS in 2010 using passive dosimeters.…”

“…In addition; only a reliably measured dataset for radiation exposure and the variation of the radiation load enables us to (a) use this data as input for radiation model and benchmark calculations ) and (b) work toward a reasonably good radiation risk estimation for future long duration space missions (Durante & Cucinotta 2011). The radiation environment onboard the ISS has been monitored since the beginning of the ISS era with various active and passive radiation detector systems (see reviews in : Berger 2008;Caffrey & Hamby 2011;Narici et al 2015) aiming for exact area monitoring within (Kodaira et al 2014) and outside the ISS . Furthermore; various experiments aimed at determining the effective dose equivalent using phantoms for the improvement of radiation risk estimations have been performed (see for example: Reitz et al 2009;Berger et al 2013, Puchalska et al 2014).…”

The radiation environment encountered in space differs in nature from that on Earth, consisting mostly of highly energetic ions from protons up to iron, resulting in radiation levels far exceeding the ones present on Earth for occupational radiation workers. Since the beginning of the space era, the radiation exposure during space missions has been monitored with various active and passive radiation instruments. Also onboard the International Space Station (ISS), a number of area monitoring devices provide data related to the spatial and temporal variation of the radiation field in and outside the ISS. The aim of the DOSIS (2009DOSIS ( -2011 and the DOSIS 3D (2012-ongoing) experiments was and is to measure the radiation environment within the European Columbus Laboratory of the ISS. These measurements are, on the one hand, performed with passive radiation detectors mounted at 11 locations within Columbus for the determination of the spatial distribution of the radiation field parameters and, on the other, with two active radiation detectors mounted at a fixed position inside Columbus for the determination of the temporal variation of the radiation field parameters. Data measured with passive radiation detectors showed that the absorbed dose values inside the Columbus Laboratory follow a pattern, based on the local shielding configuration of the radiation detectors, with minimum dose values observed in the year 2010 of 195-270 lGy/day and maximum values observed in the year 2012 with values ranging from 260 to 360 lGy/day. The absorbed dose is modulated by (a) the variation in solar activity and (b) the changes in ISS altitude.

“…For example, the FNTD technology can be applied to determine the biological response in a mix-beam radiation field, where cells targeted with radiation at different LETs demonstrate synergistic biological effects [ 21 , 22 ]. Radiation exposures in space and also during clinical therapy are representative examples of the mix-radiation environment [ 21 – 23 ].…”

The geometric locations of ion traversals in mammalian cells constitute important information in the study of heavy ion-induced biological effect. Single ion traversal through a cellular nucleus produces complex and massive DNA damage at a nanometer level, leading to cell inactivation, mutations and transformation. We present a novel approach that uses a fluorescent nuclear track detector (FNTD) for the simultaneous detection of the geometrical images of ion traversals and DNA damage in single cells using confocal microscopy. HT1080 or HT1080–53BP1-GFP cells were cultured on the surface of a FNTD and exposed to 5.1-MeV/n neon ions. The positions of the ion traversals were obtained as fluorescent images of a FNTD. Localized DNA damage in cells was identified as fluorescent spots of γ-H2AX or 53BP1-GFP. These track images and images of damaged DNA were obtained in a short time using a confocal laser scanning microscope. The geometrical distribution of DNA damage indicated by fluorescent γ-H2AX spots in fixed cells or fluorescent 53BP1-GFP spots in living cells was found to correlate well with the distribution of the ion traversals. This method will be useful for evaluating the number of ion hits on individual cells, not only for micro-beam but also for random-beam experiments.
