The lab highly recommends NOT to send powdered bones.
Bones that have been drilled or powdered prior to submission may not lend themselves to a robust pretreatment that can ensure the accuracy of the results.
The Beta Analytic lab is located in Miami, Florida. Samples can be sent directly to Miami or to any of its sample forwarding offices worldwide.

The Radiocarbon Revolution Since its development by Willard Libby in the 1940s, radiocarbon (14C) dating has become one of the most essential tools in archaeology.
If bones have been exposed to water over a long period of time, it’s likely that the teeth will be more suitable for dating.
The tooth enamel will have protected the dentin from loss.
Miami radiocarbon lab Beta Analytic offers AMS dating for bones and teeth.
The lab no longer provides radiometric dating for these samples.Most of the time, the collagen proteins had been leached out of the bone leaving them unsuitable for radiocarbon dating.Leached bones are commonly white, brittle, or friable that may crumble when slight pressure is exerted on them.However, as with any dating technique there are limits to the kinds of things that can be satisfactorily dated, levels of precision and accuracy, age range constraints, and different levels of susceptibility to contamination.Radiocarbon dating is especially good for determining the age of sites occupied within the last 26,000 years or so (but has the potential for sites over 50,000), can be used on carbon-based materials (organic or inorganic), and can be accurate to within ±30-50 years.If there is no other choice but to send powdered bones, please make sure that the bones must be cleaned of any adhering or invasive contamination prior to the drilling or powdering.
