  • radiation hardness
    sub-micron technologies tend to be more resistant to total dose effects than older technologies (in some cases up to several hundred Krad). High performance analog devices ( e.g. amplifiers, ADC, DAC) may though potentially be affected at quite low doses. Total dose is measured in Rad or Gray ( 1 Gray...
  • Radiation-Hardened Motors
    Motion control in radiation-intensive environments poses a serious challenge to the design engineer. Conventional step and microstepping motors are susceptible to high-energy gamma radiation particles that will attack the motor materials. Usually, the organic compounds are most susceptible...
  • Radiation Sterilization of Polycarbonate-Polyestercarbonate Copolymers (.pdf)
    . polycarbonate-polyestercarbonate copolymers show that. excellent clarity, good mechanical properties, and high. the color shift after irradiation decreases with increasing. impact strength.

  • A Comparison of Spectroradiometers to Radiometers for UV Radiation Measurements
    climatology. in over 40 sites worldwide since 1973. Purpose of UVMonitoring UVB,. radiation shorter than 320 nm., is important biologically. The high photon. energy of the UVB can damage DNA. The effects of this damage varies with the. specie, the UVB intensity, and with the total dose. The spectral...
  • The Accurate Measurement of Biological Effective Ultraviolet Radiation
    at the International Symposium on High Latitude Optics , Tromsö, Norway, July 1993. towards shorter wavelengths in the region of 290-340 nm. For many there is a characteristic UVA plateau. It is often. difficult to establish a unique action spectrum for a photobiologic process because there may...

    high resolution while remaining as small as possible in order to meet the packing. requirement. Further, these encoders must be modified to be radiation resistant as the high field. dose would destroy conventional encoder technology. Varian's radiation system was designed to deliver distinct radiation...

    , similar to a video camera that's able to switch from movie mode to taking high-resolution single pictures. He's also experimenting with applying the technology to tomosynthesis, a way of producing localized 3-D digital X-rays. Applications for tomosynthesis include breast X-rays but with much higher...
  • FTIR Analysis of Crosslinked Polyethylene (.pdf)
    A discussion of the use of Fourier-transform infra-red spectroscopy to measure the concentration of a chemical structure that is generated during the irradiation of polyethylene. This technique indicates the uniformity of radiation dose and absolute absorbed radiation in ultra-high molecular weight...
