Embodiment 1
[0018] A kind of method for quickly discriminating seawater and freshwater pearl powder, carries out as follows:
[0019] (1) Take a commercially available pearl powder sample of about 0.5g and put it in a white transparent plastic bag;
[0020] (2) sending the plastic bag that the pearl powder sample is housed into the cobalt-60 gamma irradiator with a source capacity of 1000k curies after irradiating for 12 hours, making the irradiation dose reach 10kGy;
[0021] (3) The pearl powder sample is taken out from the plastic bag and observed. The pearl powder that turns gray and black is freshwater pearl powder, and the one that does not change color is seawater pearl powder.
Embodiment 2
[0023] A kind of method for quickly discriminating seawater and freshwater pearl powder, carries out as follows:
[0024] (1) Take a commercially available pearl powder sample of about 0.5g and put it in a white transparent plastic bag;
[0025] (2) send the plastic bag that the pearl powder sample is housed into the cobalt-60 gamma irradiation device that packs source capacity and be 1500K curie after 8 hours of irradiation, make irradiation dose reach 10kGy;
[0026] (3) The pearl powder sample is taken out from the plastic bag and observed. The pearl powder that turns gray and black is freshwater pearl powder, and the one that does not change color is seawater pearl powder.
Embodiment 3
[0028] A kind of method for quickly discriminating seawater and freshwater pearl powder, carries out as follows:
[0029] (1) Take a commercially available pearl powder sample of about 0.5g and put it in a white transparent plastic bag;
[0030] (2) after sending the plastic bag that pearl powder sample is housed into the cobalt-60 gamma irradiator that packs source capacity to be 2000k Curies, after irradiating for 6 hours, make irradiation dose reach 10kGy;
[0031] (3) The pearl powder sample is taken out from the plastic bag and observed. The pearl powder that turns gray and black is freshwater pearl powder, and the one that does not change color is seawater pearl powder.
