Find out how to prepare and submit your samples for analysis at the 果冻影院 Environmental Radiometric Facility, including key requirements and procedures.
Before sending samples for analysis it is important to contact either the Facility Manager听Dr Handong Yang, the Financial Coordinator听Jamahl Holland, or the Academic Coordinator听Dr Lucy Roberts听regarding up-to-date costs and the time from receipt of samples to reporting as this can vary depending on demand. When submitting samples, please consider the following requirements:
- Basic Information
- Site name
- Location (Latitude; longitude)
- Sampling date
- Samples
- For sediment analyses, we require 0.5g dry mass of each sample as a minimum. Please send around 2g for each sample if possible听as this can reduce counting time for samples with low-level radionuclide activity and also reduces counting errors derived from the background.
- For core dating work, it is also a good idea to send as many samples as possible at the start. If during the analysis we find we need to request additional samples from you, this can considerably increase the time it takes to complete the work and send you a report.
- Samples should be submitted dry. Freeze-drying or air-drying are both fine.
- Data
For sediment and soil core samples dry density data are required for the core as these are used for calculating radionuclide inventories. If you do not have these data, sediment dry density may be calculated from the sample鈥檚 dry weight (or water content) and the wet density. Please do send us an e-mail if you have any questions about this.
- Quality Control
A document covering the Standard Operating Procedures for our laboratory is available upon request.
- Sending and Returning Samples
- Please send your samples to The Department of Geography, North-West Wing, 果冻影院, Gower Street, London WC1E 6BT, UK. Please mark for the attention of either听Dr Handong Yang听辞谤听Dr Lucy Roberts.
- The analysis is non-destructive and we are happy to return your samples, so do let us know if you want them sent back to you after the analysis is complete.
