One millimeter hair samples along the length of the hair were taken from the subject and analyzed using neutron activation analysis (MIT, Massachusetts). Every millimeter represents about 2 days. The subject's arsenic levels are within the normal range for the period of approximately 30 days prior to the date the samples were taken.
