ESR offers a range of services for determining radioactivity content in a range of sample types such as food, water, soil, sediment, mining ore and products, environmentalbiota, sediment and air samples.Some countries may also require testing of a 100% New Zealand product.Electron spin resonance: The identification of paramagnetic species through absorption of energy in an external magnetic field.Common techniques in chemistry and physics, defined by the relevant range of the electromagnetic spectrum, are optical spectroscopy, infrared (IR) spectroscopy, and ultraviolet (UV) spectroscopy.ESR spectroscopy almost always involves absorption of energy in the microwave region.For the past 50 years, ESR's specialised environmental radiochemistry laboratory has been measuring naturally occuring and man-made radionuclides.

The ring monitor is suited to measuring doses to the fingers and hands.

Our service has a 60 year history of operation and is the only service of its kind based entirely in New Zealand.

For more information: ESR offers a range of measurement services to determine and quantify the presence of potential radioactive contamination.

Since then applications have been developed in multiple fields of chemistry and physics, as well as the potential for dating in geology, paleontology, and archaeology. Quantum theory tells us that all systems have a definite energy.

Every spectroscopic method involves transitions between two states due to input of energy to a material.
