## 1 Introduction  
High-intensity lasers have progressively been used in contemporary research for the study of matter under extreme conditions and to generate beams of accelerated particles [1; 2; 3; 4; 5; 6]. As result of the interaction of high-power laser pulses (I \(>\) 10\({}^{19}\) W/cm\({}^{2}\),_fs_ to _ps_ pulse duration) with solid micrometer flat [1; 2] or structured thin targets [2; 6], by the target normal sheath acceleration (TNSA) mechanism, electron and proton beams with high directionality, small divergence, and energies up to tens of MeV [1; 2; 3; 4; 5; 6] are generated. The TNSA regime involves complex physical phenomena and is usually considered to be the main rear surface ion acceleration mechanism. When the laser pre-pulse interacts with the target's front side,it produces a pre-plasma. The subsequent arrival of the main laser pulse leads to the generation of hot electrons, as the pre-plasma electrons absorb a percentage of laser pulse energy. The mean free path of such hot electrons in the target is larger than its thickness, and thus part of them pass through the target and form a dense sheath of negative charge in the proximity of the target rear surface up to its rear surface, where it generates a dense sheath. The further expansion of the electrons sheath into the vacuum determine a TV/m electric field, normal to the target surface. The impurities (water and organic molecules) adsorbed on the rear side of the target can be ionized in this strong electric field. Thus, the generated protons are accelerated in the normal direction to the target. Besides electron and proton beams, bremsstrahlung radiation is also produced due to electron interaction with target nuclei [2]. At the same time, X-ray bremsstrahlung photons can be provided by the \"hot\" electrons and laser accelerated electrons which reach the vacuum chamber walls [7; 8]. The mixed field of photons and electrons might create a hazardous radiation environment, as dose levels of tens of mGy/per laser shot, depending on the target thickness and material characteristics, can be obtained [7; 8]. In order to distinguish between different kinds of laser accelerated particle beams, complex detection systems needed to be envisaged. For such goals, magnetic or Thomson parabola spectrometers coupled with Lanex foils, image plates, radiochromic films (RCF), microchannel plates, or CR-39 detectors have been used [2; 9; 10; 11]. These spectrometers, placed at different distances and angles with respect to the laser-target interaction point, can reveal the energy spectral distribution of the electron and proton beams. The spectra of photons emitted in TNSA regime can be measured using X-ray spectrometers and estimated from the energy distribution of electron beams [12]. The charts of electron-photon distribution in the mixed field of radiation were calculated and experimentally determined [7; 8]. It was shown [5] that the spectral distribution of laser accelerated particle beams in high power laser-solid target experiments can reproduce the space radiation environment. The values of radiation dose per laser shot measured during such experiments, inside the target vacuum chambers [7; 8], are similar to those measured onboard space vessels [13; 14; 15; 16; 17; 18]. On the NASA website [13], daily values of hundreds of \(\upmu\)Gy were reported for the cumulative radiation dose inside spacecrafts. Similar conditions can be obtained using laser plasma accelerator facilities available worldwide [19; 20; 21; 22]. Inside the spacecrafts and space stations there are lots of electronic systems that need to be tested in dedicated facilities on Earth, before being used in extreme conditions. In addition, the assessment of detectors' response in ground-based facilities is essential for overcoming the problems intrinsic to space dosimetry. As shown in [PERSON]'s et al. paper [5], to test electronics, a proper knowledge of the fluxes of ionizing radiation is an important issue.
