Six bone samples obtained from the Mannar mass grave have been sent to Florida for beta analytics.
The results of the carbon testing are expected to be communicated to the Sri Lankan authorities in three weeks.
Radiocarbon dating calculates the amount of Carbon-14 in bone and teeth samples and establishes the approximate time when an animal or plant was alive. It is a form of testing used in archaeology and forensic science for dating human remains.
“The samples from the Mannar mass gravesite will be sent to a laboratory abroad specializing in bomb pulse carbon 14 technique. In cases where the skeletons belonged to persons that died after World War II, bomb-pulse carbon 14 dating can provide a narrower range of time periods in which the deaths occurred,” the OMP said, in a statement last month.
Authorities have unearthed two hundred and seventy-eight skeletons, which includes remains of men, women and children.
Although there are some damages to the bones, judicial medical experts have claimed that it is only upon further investigation that we can determine if these are antemortem or postmortem injuries, and whether it relates to the cause of death.
