The tasks of the Chang'e-4 include astronomical observation, surveying the moon's terrain, landform and mineral composition, and measuring the
neutron radiation and neutral atoms to study the environment on the far side of the moon, the China National Space Administration has said.
The mission will perform low frequency radio astronomical observation, terrain and relief analysis, detection of mineral composition and shallow lunar surface structure, the measurement of
neutron radiation and neutral atoms to study the environment on the hidden side of the Moon.
The current work assesses the effects of
neutron radiation on a multicore processor which does not implement protection mechanisms in its internal memories.
Due to: the fact that values of cross section strongly vary in energy for various reactions, the differences in these reactions in the tissue and the detector, the 2-step process of transferring the energy of neutrons to the medium, and the weighting factor ([w.sub.R]) varying over a wide range of radiation-[w.sub.R] means that the dose measurements of
neutron radiation are difficult and the result is not as accurate as in the case of photon-radiation dosimetry.
It covers various types of radiation, how it is generated, how it interacts with matter, and how healthy tissue can be protected against unsafe radiation levels; the main imaging modalities using ionizing radiation (x-ray radiography, scintigraphy, and PET (positron emission tomography)); the life cycle of cells, cancer development, and the main concepts and methods for radiation treatment, namely x-ray radiotherapy, proton and
neutron radiation therapy, and brachytherapy; and laser treatment applications, the application of multifunctional nanoparticles, and prosthetics for limbs, stenosis, and the visual and auditory senses.
Because of their high hydrogen content, they are also used as
neutron radiation shielding material in casks for transport and/or storage of radioactive material [2, 3].
Kromek will develop an advanced personal detection system for gamma and
neutron radiation, kit that can be combined with other such systems to form large networks, providing information on radiation signatures over an extended area - thereby picking up on anomalies in cities that could indicate an act of terrorism, such as a 'dirty bomb'.

Just as alcoholic drinks, diesel engine exhaust,
neutron radiation and plutonium do.
Working with the ISIS pulsed neutron and muon source, ChipIR is designed to look at how silicon microchips respond to cosmic
neutron radiation, with consequent benefits for the electronics industry.
