“…TEPCs are routinely flown on board the Space Shuttle and ISS (4)(5)(6). Recently a silicon-based LET spectrometer called the Realtime Radiation Monitoring Device (RRMD-III) has been developed and flown on three Space Shuttle missions (7,8). Both of these detectors have the capability to measure dose rate and estimate radiation quality for charged particles with LET ranging from 0.2 to 700 keV/m.…”

Experiments have been performed to measure the response of a spherical tissue-equivalent proportional counter (TEPC) and a silicon-based LET spectrometer (RRMD-III) to protons with energies ranging from 50-200 MeV. This represents a large portion of the energy distribution for trapped protons encountered by astronauts in low-Earth orbit. The beam energies were obtained using plastic polycarbonate degraders with a monoenergetic beam that was extracted from a proton synchrotron. The LET spectrometer provided excellent agreement with the expected LET distribution emerging from the energy degraders. The TEPC cannot measure the LET distribution directly. However, the frequency mean value of lineal energy, y(-)(f), provided a good approximation to LET. This is in contrast to previous results for high-energy heavy ions where y(-)(f) underestimated LET, whereas the dose-averaged lineal energy, y(-)(D), provided a good approximation to LET.

“…The ratio obtained in the BBND experiment is greater than the prediction in 500 km orbital altitude (Armstrong and Colborn, 1998), and the result for charged particles (e.g. Cucinotta et al, 2000;Doke et al, 2001). (Some experiments referred to above measured the radiation dose from both charged particles and neutrons.…”

“…[8][9][10][11] However, in an anisotropic radiation field their strongly anisotropic sensitivity might cause the under-or overestimation of the doses. For this reason the development of a three dimensional silicon detector telescope (TRITEL) with almost uniform sensitivity in 4 got underway at the former MTA KFKI Atomic Energy Research Institute (now MTA Centre for Energy Research) in cooperation with BL-Electronics Ltd. in the past years.…”

The cosmic radiation field in space is rather complex in terms of composition and with respect to energy of the constituent particles. The intensity and energy spectrum of the cosmic radiation may considerably change with time as well. A three dimensional silicon detector dosimetry telescope (TRITEL), with sensitivity in 4 , has been recently developed in the Centre for Energy Research, Hungarian Academy of Sciences. The instrument comprises three mutually orthogonal, fully depleted, passivated implanted planar silicon detector pairs and it is designed to measure the energy deposit of charged particles. From the time spectra and the deposited energy spectra measured, the flux of charged particles, the absorbed dose, the linear energy transfer (LET) spectra and the average quality factor of the cosmic radiation, as well as the dose equivalent can be determined. This way the stochastic biological effects of the cosmic radiation in orbit can be characterized. Measurements have been already performed in the stratosphere on research balloons and on board the International Space Station (ISS). The orbit of RISESAT (Rapid International Scientific Experiment Satellite) gives an excellent opportunity to measure the dosimetric quantities listed above at higher altitudes and higher latitudes than at which the ISS is orbiting around the Earth.
