Our equipment has a very high efficiency and ultra-low background so can be used to measure tiny amounts of radionuclides. Sedimentology of a debris-rich, perhumid valley glacier margin in the Rakaia Valley, South Island, New Zealand.

We therefore welcome projects where low-level radioactivity is expected such as sediments from New Zealand and the Pacific Islands. Standard Rate Standard rate for routine work with priority processing: NZ00 + GST per sample.

This price includes all irradiation and luminescence measurements required to obtain the equivalent dose, and high resolution laboratory gamma-spectrometry for dose rate determination.

The other room houses most of the modern electronic equipment, including: Please contact Ningsheng Wang (MSc.) for more information.

Our luminescence dating service is available for researchers in New Zealand and overseas.

The Risø TL/OSL reader for luminescence dating On this page: The laboratory is set up in dark rooms with extremely subdued orange illumination.

One room serves as preparation laboratory, where all incoming samples are unpacked and chemically treated to purify the sample and extract the desired minerals in the right grain size.

Gammaspectrometry We are also involved in research projects requiring gammaspectrometry.

Applications involve measurement of artificial radionuclides in sediments (such as Pb.

Optically Stimulated Luminescence We use optically stimulated luminescence (OSL) to date aeolian, fluvial, lacustrine and shallow water marine sediments, as well as most quartz or feldspar-bearing objects, which have seen sunlight or intense heat during deposition.

These sediments can be used to study ancient earthquakes, tsunamis, flooding and volcanic eruptions, as well as climate change, glaciation and tectonic uplift.

The Luminescence Dating Facility at Victoria University is the only one of its kind in New Zealand and is led by Prof Rewi Newnham and Ningsheng Wang.

It is primarily a research facility for the School and for collaborators in New Zealand. The atmospheric lead record preserved in lagoon sediments at a remote equatorial Pacific location: Palmyra Atoll, northern Line Islands.
