Compact Tissue-equivalent Proportional Counter for Deep Space Human Missions
Effects on human health from the complex radiation environment in deep space have not been measured and can only be simulated here on Earth using experimental systems and beams of radiations produced by accelerators, usually one beam at a time. This makes it particularly important to develop instruments that can be used on deep-space missions to measure quantities that are known to be relatable...
متن کاملRadial dependence of lineal energy distribution of 290-MeV/u carbon and 500-MeV/u iron ion beams using a wall-less tissue-equivalent proportional counter
Using a wall-less tissue-equivalent proportional counter for a 0.72-μm site in tissue, we measured the radial dependence of the lineal energy distribution, yf(y), of 290-MeV/u carbon ions and 500-MeV/u iron ion beams. The measured yf(y) distributions and the dose-mean of y, [Formula: see text], were compared with calculations performed with the track structure simulation code TRACION and the mi...
متن کاملThe response of a spherical tissue-equivalent proportional counter to iron particles from 200-1000 MeV/nucleon.
The radiation environment on board the space shuttle and the International Space Station includes high-Z and high-energy (HZE) particles that are part of the galactic cosmic radiation (GCR) spectrum. Iron-56 particles are considered to be one of the most biologically important parts of the GCR spectrum. Tissue-equivalent proportional counters (TEPCs) are used as active dosimeters on manned spac...
متن کاملIntroducing a bony composite as tissue equivalent for radiotherapy phantoms
The use of a device that simulates the actual condition, as well as being equivalent to the human body in materials and tissues, and having the capability of acting like internal motions of human body is necessary to investigate and simulate the motion of a tumor in radiotherapy and to evaluate dosimetrical coverage of the dynamic target. This device which is called the dynamic phantom should s...
متن کاملMeasurement of the neutron fluence and dose spectra using an extended bonner sphere and a tissue-equivalent proportional counter.
A conventional Bonner Sphere (BS) set consisting of six polyethylene spheres was modified to enhance its response to a high-energy neutron by putting a lead shell inside a polyethylene moderator. The response matrix of an extended BS was calculated using the MCNPX code and calibrated using a 252Cf neutron source. In order to survey the unknown photon and neutron mixed field, a spherical tissue ...
