Evaluating the BD-100R as a neutron spectrometer through pressure variation

Investigators have evaluated the dose response of neutron bubble dosimeters for possible use as a personnel monitor. In addition, two types of neutron spectrometer devices using bubble dosimetry have been developed. One uses the variation of vapor pressure of mixtures of detection material to extract the neutron energy spectrum, while the other employs variation of applied pressure on a different material. Dosimeter response changes due to variation of applied pressure have been demonstrated by Ing and Birnboim at absolute pressures of 0.432 MPa and atmospheric pressure. This investigation is intended to demonstrate the determination of an unknown spectrum utilizing the dosimeter response (number of bubbles formed) as a function of the applied pressure
