||2000: Samut Prakan radiation accident: the part of the radiation therapy unit containing the radiation source was acquired by two scrap collectors, who claimed to have bought it from some strangers as scrap metal for resale. They took it home, planning to dismantle it later. On 1 February, the two, together with another two associates, attempted to dismantle the metal part (a 97-kilogram, 42-by-20-centimetre lead cylinder held in a stainless steel casing), which was the unit's source drawer. Using a hammer and chisel, they only managed to crack the welded seam. Two of the men then took the metal piece, along with other scrap metal, to a scrapyard on Soi Wat Mahawong in Phra Pradaeng District, Samut Prakan Province. There they asked a worker at the scrapyard to cut open the cylinder using an oxyacetylene torch. As the cylinder was cut open, two smaller cylindrical metal pieces, which had held the source capsule, fell out. The worker retrieved the two pieces and kept them in the scrapyard, but was unaware of the source capsule itself. The lead cylinder was returned to the scrap collectors for them to complete the disassembly. https://en.wikipedia.org/wiki/Samut_Prakan_radiation_accident
