Volcano Art Prize (VAP) 2024 Entry by Elizabeth
O’Brien. Title: pXRF Bone Lead Testing
Lead Safety Message: #Grandma Lead says: In our
lead safe future, everyone will have access to bone
lead testing by portable X-Ray Fluorescence (pXRF)
using a Niton XL3t GOLDD+ (made by Thermo-
Fisher Scientific, USA). And all earthlings should
have less lead in our bones if Australian registered
voters sign the Circular Economy for Lead Petition
EN6714. Description of Work: iPhone 13 photo and
text added in Powerpoint. Petition EN6714 is at
https://www.aph.gov.au/e-
petitions/petition/EN6714 until Wed 04 Dec 2024
11:59 PM (AEDT).

At the 11th November 2024 Annual General Meeting of The LEAD Group, I informed
members that US$37,000 could buy a Niton Thermo Fisher XL3t+ GOLDD+ XRF scanner
and that Dr Aaron Specht has been using these machines for a decade and has published
some 20 journal articles on his results, as well as being available to either validate the
portable XRF (pXRF) machine in the US or to have his costs covered to validate it in
Australia. pXRF machines are normally used for mining exploration, but Aaron Specht has
led the academic world in their use to assess bone lead burdens. For research use by
academics (perhaps in combination with an Australian pathology company, lead mine or lead
poisoning prevention centre such as are found in Port Pirie lead smelter town, South
Australia or Broken Hill lead mining town, New South Wales, or Mt Isa lead smelter and lead
mining town, Queensland) would need ethics approval.
I added that these Niton pXRF scanners could be used to measure bone lead burden in
mining and smelting towns to assess the effectiveness of detoxification methods. The
accuracy is linked to the thickness of skin over the tibia – the less fat the more accurate the
bone lead XRF result. They can also be used to measure lead in wildlife that have eaten or
been shot with lead shot.
Tim Pye asked if it is safe to point x-rays at living people. I assured the meeting that this is
safe and would thus pass ethics approval. It would be a long-held dream of mine come true if
the first person pXRF bone lead tested in Australia would be Martin Bryant, the Port Arthur
Massacre shooter who began serving 35 consecutive life sentences in prison in Tasmania after
he was found guilty of 35 shooting deaths in 1996.
After I sent the following email to Aaron Specht, he replied with the next two
articles so our Project to ensure that a has been launched!!
