The present study focuses on determination of alpha particles concentration in different samples
of toothpaste by using nuclear track detector (CR-39). Nine samples of toothpaste have been collected
from local Iraqi markets in Babylon Province. These samples have been chosen according to
their most commonly use in Babylon Province. The samples were kept with CR-39 detector for six
weeks period and then etched by 6.25 N of NaOH solution at temperature of 60˚C for 5 hours. The
results of the present work show that Sample 3 (Frosty) found to have a high alpha concentration
about four times compared with Sample 4 (Aquafresh) and about 2 - 3 times compared with other
samples.
