ā€œLow-background metals are valuable because they carry particularly low levels of radiation. Used as shielding in advanced particle physics projects and medical science devices like X-ray chambers, these metals wonā€™t interfere with specialized, highly radiation-sensitive tools.ā€
2/ā€œMost steel is made by blowing air or pure O2 into molten pig iron to remove impurities & make it stronger. Since start of atmospheric nuclear tests, all air-even purified O2, contains elevated levels of isotopes like cobalt-60,most new steel is infused w/radioactive particles.

1/20 Good afternoon. Iā€™m Antony Firth and Iā€™m going to tweet about ā€˜Steel on the Seabedā€™. Iā€™ll be referencing work with @HistoricEngland @HE_Maritime @honor_frost @SouterNT @HeritageFundNE @citizan @IoSIFCA @tynetotees @ukchp. Many thanks to all & to organisers of #SWOS20! Image
2/20 By ā€˜Steel on the Seabedā€™ I mean #shipwrecks from the period c. 1850-1950 ā€“ a period of numerous radical transformations in ships but also in the communities whose lives they touched. These historic steel artefacts within the marine environment still reverberate. #SWOS20
3/20 In 1832 before most were even built, Lyell surmised ā€˜It is probable that a greater number of monuments of the skill and industry of man [sic] will be collected together in the bed of the ocean than will exist at any other time on the surface of the continentsā€™. #SWOS20 Image

Two of the many boats in distress in the Central #Mediterranan that reached out to the Alarm Phone in November went missing. We fear that these are two invisible & silenced #shipwrecks that #European authorities refuse to acknowledge. Image
On November 21, 94 people fleeing from #Libya alerted us when their rubber boat was deflating. Two #NGO vessels, #OpenArms and #AitaMari, searched all night in vain. #EU authorities refused to respond to the distress & to acknowledge a potential shipwreck.
On November 29, a blue wooden boat with 70 people alerted us from #Malta #SAR zone as water was entering the boat. We alerted European authorities & #AlanKurdi. We were told that @Armed_Forces_MT searched for the boat & couldn't find it. Since then, no answers, only silence.
