☆ Fact Check-Pregnancy ultrasound does not cause the DNA damage of ‘250 chest x-rays’

The text in one post sharing the claim (here) reads, “A Single Exposure to Ultrasound Causes DNA Damage Similar to 250 Chest X-Rays” overlayed on an ultrasound image of a fetus. A URL printed across the fetus image leads to an article (here) that makes unfounded claims about the risk of fetal ultrasound, and cites a 1981 study for the “250 chest x-rays” figure. The 1981 study did not draw any such conclusion. In response to a request for comment, the author of the article Jeanice Barcelo said she stands by her claim about the 1981 study. A 1981 study of mouse cells in test tubes did not conclude that ultrasound caused DNA damage equivalent to that of hundreds of x-rays, and extensive research finds ultrasound to be safe for use during pregnancy.

☆ How do you lose a radioactive capsule? Australian investigators are wondering too
▼ + stars: | 2023-02-02 | by ( Hilary Whiteman | ) edition.cnn.com time to read: +8 min

Brisbane, Australia CNN —The discovery of a tiny lost radioactive capsule beside a remote highway in Western Australia raises many questions – not least how it escaped layers of radiation-proof packaging loaded onto a moving truck. Under the Radiation Safety Act 1975, only specially trained and licensed operators can package radioactive substances, but different rules apply to contractors hired to transport it, Steen said. “Any transport company can transport radioactive material provided they have got the license to do so,” she said. Staff from the National Emergency Management Agency, the Australian Nuclear and Science Technology Organization and the Australian Radiation Protection and Nuclear Safety Agency also took part. This time, it traveled in a convoy of enclosed white vehicles – with big stickers warning of the presence of a radioactive substance.

☆ Australia’s Nuclear Safety Agency Joins the Hunt for Missing Radioactive Capsule

ADELAIDE, Australia—Authorities intensified their search for a missing capsule containing radioactive material in Australia’s far west, deploying car-mounted detection equipment for the first time as they began to retrace a truck’s nearly 900-mile journey across the Outback. The capsule, which is less than a third of an inch long and contains Cesium-137, is believed to have fallen from a truck somewhere between Rio Tinto PLC’s Gudai-Darri mine and Perth, the capital of Western Australia. An initial search using hand-held radiation monitors failed to find the capsule, which was discovered to be missing on Jan. 25, prompting a public health alert.

MELBOURNE, Jan 31 (Reuters) - Australia’s nuclear safety agency said on Tuesday it had joined the hunt for a radioactive capsule missing in the west of the country. Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) is working with the Western Australian government to locate the capsule, it said in a statement. The capsule, believed to have fallen from a truck, was part of a gauge used to measure the density of iron ore feed which had been entrusted to a specialist contractor to transport. The loss may have occurred up to two weeks ago. Reporting by Melanie Burton in Melbourne Editing by Alasdair PalOur Standards: The Thomson Reuters Trust Principles.

The Department of Fire and Emergency Services said on Monday that it would take five days to retrace the road train's route. Authorities suspect vibrations from the road train caused the screws and a bolt from the gauge to come loose, and then the capsule fell out. A member of the Incident Management Team coordinates the search for a radioactive capsule that was lost in transit by a contractor hired by Rio Tinto, at the Emergency Services Complex in Cockburn, Australia, in this undated handout photo. Department of Fire and Emergency Services/Handout via REUTERSCenturion said in a statement that the capsule was dislodged from equipment contained in a crate. "The equipment can detect radiation emitted by the missing capsule and is currently being used around the Perth metropolitan area and outskirts."

☆ Explainer: How did a radioactive capsule go missing in Australia and how dangerous is it?

SYDNEY, Jan 31 (Reuters) - Australian authorities are mounting an extensive search for a tiny radioactive capsule believed to have fallen out of a road train - a truck with multiple trailers - that travelled 1,400 km (870 miles) in Western Australia. When it was unpacked on Jan. 25, it was found broken apart, with one of its four mounting bolts as well as screws and the capsule missing. Authorities suspect vibrations from the road train caused the gauge to break apart and the capsule fell out. The road train travelled from the mine in the state's remote Kimberley region and arrived at a storage facility in the suburbs of Perth on Jan. 16. The search involves at least five other government agencies including the Department of Defence, the police, the Australian Nuclear and Science Technology Organisation and the Australian Radiation Protection and Nuclear Safety Agency.
