Characteristics of Synchrotron Radiationonly called “synchrotron radiation” because first observed in the visible region, at the 70 MeV small electrosynchrotron, by a research group working in 1947 at the General Electric Research Laboratory (Schenectady — N.Y.).Medicaid 发表于 2025-3-27 03:23:59

Quantitative Determination of Ultraviolet Radiationent has not been feasible until the last few years when quality instruments have become accessible. The problem has historically been the separation of the UVR from the visible and infrared portions of the optical spectrum and then accurately weighting the UVR to the documented human biological resp睨视 发表于 2025-3-27 19:53:00
Measurements of Welding Arcs and Plasma Arcse ultraviolet output is therefore potentially hazardous. As is well known the visible radiation emitted by these arcs is blinding, and several cases of severe retinal burns are known to have caused blindness. Theoretically, the emitted infrared radiation should be substantial, giving rise to concern永久 发表于 2025-3-27 22:20:57
