Production at Australia’s only nuclear medicine facility halted after ‘safety incident’ Production has ceased and an urgent investigation has been launched after two employees at a newly opened Australian nuclear medicine facility at Lucas Heights were exposed to an unsafe dose of radiation late last week.Just two weeks after it was granted a licence to enter into full domestic production, the Australian Nuclear Science and Technology Organisation (Ansto) has confirmed production at its new $168m nuclear medicine facility has been halted after “a safety incident” on Friday morning.

Ansto said three of its workers were “attended to by radiation protection personnel” after the incident, in which contamination was detected on the outside of a container holding 42 millilitres of the radioisotope molybdenum-99 (Mo-99).

Two of those workers received a radiation dose above the legal limit roughly equivalent to a conventional cancer radiation therapy treatment, an Ansto spokesman said……

Located at the Lucas Heights nuclear facility in Sydney’s south, the $168m nuclear medicine facility was announced by the federal government in 2012 with the goal of tripling Australian production of Mo-99, the parent isotope of Technetium-99m. …..

It is the second contamination scare at the Lucas Heights facility in only a few months.

In March three staff at the Lucas Heights nuclear facility were taken to hospital after they were exposed to sodium hydroxide when a cap came off a pipe in the nuclear medicine manufacturing building. https://www.theguardian.com/australia-news/2019/jun/24/two-workers-exposed-to-unsafe-radiation-dose-at-lucas-heights-nuclear-facility
