Sample Submission Guidelines

BEFORE commissioning analyses, contact the laboratory (legal@usp.br) to consult on the suitability of the applied methodology for your needs and to pre-schedule the analyses period. Ideally, contact the laboratory before sample collection to inform us of the location and type of sediment, and to consult on the sampling and luminescence analysis strategy. Information on sampling can be found here.

Each sample should contain the following information:

Unique sample ID (avoid using OSL-1, OSL-2, LOE-1, LOE-2, etc)
Depth below surface (in meters)
Latitude and longitude (in decimal degrees)
Elevation (in meters)
Estimated age and/or other age control
Photos, site descriptions, stratigraphic logs

Turnaround time

Please contact us to inquire about current turnaround times for specific analysis types and sample quantities. As a general guideline, the typical processing time is approximately 6 months for up to 15 samples submitted for quartz OSL-SAR dating and up to 8 samples submitted for potassium feldspar pIRIR-SAR dating. Actual turnaround times may vary depending on sample age and luminescence characteristics.

Registration for a personal radiation dosimeter

Users performing luminescence measurements must have their personal radiation dosimeter to access the luminescence reader’s room. Issuing a personal dosimeter must be requested in advance and requires certification of basic knowledge of ionizing radiation and a Brazilian CPF number for registration. Foreigners can obtain a CPF number here . Once you are scheduled to use the lab, send a copy of your CPF to legal@usp.br
