Because ARIES® is a unique world-first, it is currently protected by a worldwide patent application
(PCT/NZ2017/050018)”, and this was gained after five years of exhaustive and comprehensive testing
and verification from Australia’s leading nuclear testing authority.


We will use Cesium 137 as an example. Cesium is a member of the alkali family, which consists of elements in Group 1 (IA) of the periodic table. The periodic table is a chart that shows how chemical elements are related to each other. The alkalis include lithium, sodium, potassium, rubidium, and francium. Cesium is considered the most active metal.

The Aries device uses the magnetic properties of the isotopes and the fact that the isotopes are in motion (air-born and passing the magnetic field (protruding from the cone)
When the isotope passes through the field the isotope rotates in order to oppose the field and momentarily (during rotation) is influenced to travel along the field lines. But this moment is brief and in isolation irrelevant, however the isotope now opposes the field at 90 degrees and will travel into an opposing magnetic set less than 45 degrees and again the isotope will be influenced to oppose the field and again be momentarily influenced to travel along the field lines.
This process is emphasised by creating a vortex-shaped magnetic field added by the paramagnetic properties of aluminium and in doing so the isotopes in motion are sucked into the air filter containing a compound that absorbs the particles emitted from them and in due course are rendered inert.


Activity Standards Laboratory

The testing was performed by the standards body for radioactivity measurement in Australia. The technical function for measuring radioactivity is housed within the Activity Standards Laboratory (ASL). Radionuclide metrology scientists in ASL employ unique, highly specialised radiation detection techniques to carry out precise measurements of radioactivity without reference to a calibration.
The Australian standards body maintains the standard for the activity of radionuclides by Authorisation of the Chief Metrologist of the National Measurement Institute (NMI) under the National Measurement Act 1960. As the national authority on radioactivity standards, it is authorised to provide legally binding certificates demonstrating traceability to the Australian standard for the activity of radionuclides to our users.
Radioactivity standards have been maintained at the facility for over 50 years. A major capital investment has funded a capability upgrade enabling ASL to increase its portfolio of primary standards and keep up with the evolving metrology requirements of the Australian nuclear medicine community.


Primary standards
ASL has the facilities and capabilities to perform accurate primary standardisations of various radionuclides. These primary standards may be verified by comparison with other international radionuclide metrology laboratories

Secondary standards

Primary standards are transferred to the ASL secondary standard ionisation chamber in the form of radionuclide specific calibration factors.

  • These calibrations make up the Australian secondary standards of activity of radionuclides
  • Specialised radiation detection techniques (TDCR, 4πβγ)β and γ spectrometry
  • Precise measurements against the national standard


Australian Certified Reference Materials (ACRMs)
An ACRM is a reference material that has been certified under regulation 48 of the National Measurement Regulations 1999. An ACRM can be used to achieve traceability to the Australian national standard for radioactivity for a specific radionuclide and measurement geometry.

Australian Nuclear Medicine Traceability Program (ANMTP)

The ANMTP has been developed in response to the Australian and New Zealand Society of Nuclear Medicine (ANZSNM) expressed need for radionuclide metrology within nuclear medicine practices. The ANMTP can assist practices with regulatory compliance through technical and legal traceability to the Australian standard for important nuclear medicine based radionuclides. One of the main objectives of the program is to improve the health outcomes of Australians receiving nuclear medicine treatments through the more precise administration of nuclear medicine.

Australian Industry Becquerel Traceability Program (AIBTP)

The AIBTP is offered to radiopharmaceutical producers and provides traceability to the national standard to assist in fulfilling regulatory requirements and facilitate trade of radiopharmaceutical products.

International responsibilities

The Australian standards body is a member of the Consultative Committee for Ionising Radiation (CCRI): Section II Measurement of Radionuclides which sets the international standards for the activity of radionuclides within the Metre Convention.
The Australian standards body is also a member of the Technical Committee for Ionising Radiation (TCRI) of the Asia Pacific Metrology Programme (APMP) and the International Committee for Radionuclide Metrology (ICRM).

Up to 10% of invasive cancers are related to radiation exposure, including both ionizing radiation and non-ionizing radiation.[1] Additionally, the vast majority of non-invasive cancers are non-melanoma skin cancers caused by non-ionizing ultraviolet radiation. Ultraviolet’s position on the electromagnetic spectrum is on the boundary between ionizing and non-ionizing radiation. Non-ionizing radio frequency radiation from mobile phones, electric power transmission, and other similar sources have been described as a possible carcinogen by the World Health Organization‘s International Agency for Research on Cancer, but the link remains unproven.[2]

Exposure to ionizing radiation is known to increase the future incidence of cancer, particularly leukemia. The mechanism by which this occurs is well understood, but quantitative models predicting the level of risk remain controversial. The most widely accepted model posits that the incidence of cancers due to ionizing radiation increases linearly with effective radiation dose at a rate of 5.5% per sievert.[3] If the linear model is correct, then natural background radiation is the most hazardous source of radiation to general public health, followed by medical imaging as a close second.

Cancer is a stochastic effect of radiation, meaning that the probability of occurrence increases with effective radiation dose, but the severity of the cancer is independent of dose. The speed at which cancer advances, the prognosis, the degree of pain, and every other feature of the disease are not functions of the radiation dose to which the person is exposed. This contrasts with the deterministic effects of acute radiation syndrome which increase in severity with dose above a threshold. Cancer starts with a single cell whose operation is disrupted. Normal cell operation is controlled by the chemical structure of DNA molecules, also called chromosomes.

When radiation deposits enough energy in organic tissue to cause ionization, this tends to break molecular bonds, and thus alter the molecular structure of the irradiated molecules. Less energetic radiation, such as visible light, only causes excitation, not ionization, which is usually dissipated as heat with relatively little chemical damage. Ultraviolet light is usually categorized as non-ionizing, but it is actually in an intermediate range that produces some ionization and chemical damage. Hence the carcinogenic mechanism of ultraviolet radiation is similar to that of ionizing radiation.
