Radiation/High Energy Working Range for glasses shown above:

 

•Flux (n/cm2.sec) from 3.0x109 to 1.0x1014

  Fluence (n/cm2) from 2.0x1016 to 8.3x1020

  Exposure time 92 days

 

•1.8x106 Rad per Hr; Total Gamma dosage 1.29x109 Rad; Cobalt 60 exposure time 30 days

 

•Mixed Beam and Particle (protons; pions; electrons, neutrons and gamma rays) resulting from a 22 GeV proton beam incident on a metal target: estimated dose is bracketed by

10MRad<Dose<100 MRad.  Additional Dosage: 13 MRad of 633 KeV137 Cs x rays.

 

 

The glasses are stable in water, acid and base.
