These services can verify whether exposure to electromagnetic fields meet health and safety guidelines, such as the New Zealand radiofrequency field exposure Standard NZS 2772.99 or the guidelines published by the International Commission on Non-Ionising Radiation Protection.The measurement equipment and techniques can also be adapted for other purposes.

For the past 50 years, ESR's specialised environmental radiochemistry laboratory has been measuring naturally occuring and man-made radionuclides.

Quality assurance is vital to our laboratory work; we are accredited to international standard ISO 7025 by International Accreditation New Zealand (IANZ).

If the energy provided to the system exactly matches the difference between two states (resonance), the system can be moved from one state to a higher one, and this yields an absorption signal.

Transitions from higher to lower levels also occur, and the emitted energy again provides a measure of the difference in energy between levels.For atoms and molecules, these states can be defined by a series of quantum numbers that are related to angular momentum.ESR spectroscopy, as the name suggests, is concerned with transitions of electrons between states of differing electron spin.Applications for test results include testing of drinking waters to show radiological compliance with the New Zealand Drinking Water Standards or overseas standards, soil erosion measurements, sediment dating, and food certification for export.For more information: ESR offers a range of measurement services across the electromagnetic spectrum.Results are documented in reports which can be tailored to provide the required level of detail and explanatory material.
