A passive dosimeter for evaluating exposure to hydrogen fluoride
A passive dosimeter designed to measure exposure to hydrogen fluoride was tested under laboratory conditions over the concentration range of 0.56 - 4.47 mg HF/m super(3). The lowest concentration was chosen to be close to the Polish TLV (0.5 mg HF/m super(3)). The dosimeter consists of a Whatman No....

| Zusammenfassung: | A passive dosimeter designed to measure exposure to hydrogen fluoride was tested under laboratory conditions over the concentration range of 0.56 - 4.47 mg HF/m super(3). The lowest concentration was chosen to be close to the Polish TLV (0.5 mg HF/m super(3)). The dosimeter consists of a Whatman No. 1 filter paper impregnated with K sub(2)HPO sub(4) placed in a polyethylene holder protected by a polyethylene screen. After exposure the filter is eluted with 0.1 M sodium citrate and the fluoride concentration determined potentiometrically. |
