Infect, which is the basis principle for producing radiation-sterilized, single-use medical products, is now well established in industries worldwide (Pikaev and Woods 1994).
For instance, industrial partners such as Actel Corporation (http://www.actel.com/) or Xilinx (http://www.xilinx.com/) have been producing radiation-tolerant antifuse FPGAs for several years for high-reliability space-flight systems.
In addition, the low radiation dose rate can induce the reoxygenation and increased blood flow of hypoxic tumor volumes, thus producing radiation-induced bystander effect to kill tumor cells that can overcome the inhomogeneous distribution of radiation dose [ 6, 7].
M.R.I.'s do not produce radiation.
At the turn of the twentieth century, Ernest Rutherford discovered that heavy elements produced radiation by atomic decay, confirming that vast reservoirs of energy were stored in the atom.
Electrons of many different energies produce radiation at essentially all wavelengths, from radio through infrared, optical, and ultraviolet up to X- and gamma rays.
Decaying waste, like used fuel from nuclear reactors, upsets the structure: it produces radiation that causes atoms to shift, creating defects that can eventually lead to cracks or other problems that can affect safety.
The Xinhua news agency said thousands of residents living on the proposed route had been petitioning for a suspension of the $4.5 billion project, fearing the high-speed trains would produce radiation.
The device produced electromagnetic radiation with a wavelength of 9 micrometres, and the researchers planned to modify it in order to produce radiation with a wavelength between 30 and 300 micrometres, a region of the spectrum for which no cheap and practical lasers existed.
The principle underlying the cesium clock is that all atoms of cesium-133 are identical and, when they absorb or release energy, produce radiation of exactly the same frequency, which makes the atoms perfect timepieces.
