Detection of gamma irradiated South Sea cultured pearls
TLDR
The pearl nacre and nucleus are analyzed by separating them for the purposed of providing information about the change of CO2 − radical as growing absorbed doses and it was found out that the signal of CO 2 − radical of the nacre is more distinct than the nucleus. Expand
