NAA Results (where indicated, normal values of arsenic are listed):

Sample	Concentration	Normal Level
Blood	0.033mg/ml	0.002-0.062mg/ml
H1 (closest to scalp + root)	1.3mg/g	1-2mg/g
H2	1.4mg/g	"

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.
