A rapid method for the determination of boron in borosilicate glasses by neutron transmission has been developed. The glass sample is dissolved in 48% HF, placed in a polyethylene cell which is located near a Ra‐Be neutron source. The neutron source and sample cell are embedded in a parafEn moderator. The attenuation of the neutron flux, which can be related to the boron concentration in the cell, is monitored with a BF 3 enriched B 10 proportional counter. Boron determinations can be made in approximately 40 minutes with an accuracy of ±%. Owing to the low sensitivity (approximately 1 mg.) the major disadvantage of the method is the large sample size necessary. The method, however, is well suited for use as a quality control procedure.
