A client’s dosimeters were having a high variability of results in the high exposure range. A dosimeter is a small piece
(< ½” x ½”) of a specially treated material that is used to read exposure level to radiation. It is used in the health care and food industries.
Performed a root cause analysis to focus work on finding an effective solution
Identified two causal relationships, both which could be removed through material selection
Specified film material characteristics that would eliminate the degradation of the dosimeters at high exposure levels
Identified and sourced films for the dosimeter pouches
Set up and completed testing to verify the solution
Dosimeter read performance at higher exposure levels was greatly improved due to the revised outer pouch packaging.
