Application

 

To test protective clothing against solid airborne particles including radioactive contamination. The machine use “inward leakage in %”, ratio of the concentration of contaminant in the ambient atmosphere to the concentration of the contaminant in the suit, to evaluate the quality of protective clothing.

 

 

Feature

  1. A standard aerosol of sodium chloride particles is generated inside a test chamber in which a test subject, wearing the protective suit under test, carries out a predetermined sequence of test exercises. The inward leakage at each sampling position inside the suit is measured by means of flame photometry.We use following indicator to judge the quality of protective clothing.

    - Lijimn: inward leakage for a given test subject (i),suit(j),exercise (m) and sampling position (n)

    - Cijmn: concentration of aerosol measured at the sampling point inside the suit for a give test subject(i), suit(j(, exercise(m) and sampling position(n)

    - LS: total inward leakage per suit (average over all exercises and sampling positions)

    - LH: total inward leakage per human test subject (average over all exercises, sampling positions and suits worn by that test subject)

    - LE: total inward leakage per exercise (average over all suits and sampling positions)

    - Lp: total inward leakage per sampling position (average over all suits and exercises)

    - LEP: total inward leakage per sampling position and per exercise (average over all suits)

    -    : mean total inward leakage (average over all test subjects, suits, exercises and sampling positions)
