Effect of oxygen deficiency on response of CR-39 on board scientific balloons

Radiat Meas. 1999 Jun;31(1-6):591-4. doi: 10.1016/s1350-4487(99)00146-8.

Abstract

We should be careful about the effect of oxygen deficiency on polymeric track detectors even at balloon altitude. Results of balloon experiments and calibration experiments in a vacuum chamber at different pressures show that the effect of oxygen deficiency becomes serious at a pressure below 10 hPa.
