Environmental radioactivity measurements



Sensitive radioanalytical techniques have been developed to measure a range of radioisotopes including those in the natural uranium and thorium decay series to the lowest levels of radiometric detection. Sensitive radioanalytical instrumentations are used and dedicated to measure only low level activities to avoid cross contamination.


Applications of this type of analysis are in the areas of 'naturally occurring radioactivity in materials' such as in plants, food products, soil, sediment and water from different sources. It is important to note this facility will not accept samples with elevated levels of radioactivity to avoid contaminations in the laboratories.


Please discuss your proposal with the appropriate ANSTO Contact Scientist before submitting your proposal as they will assist you in making the correct capability selection.
