Body sites in which brachytherapy can be used to treat cancer. Brachytherapy is commonly used to treat cancers of the cervix, prostate, breast, and skin. [1]Brachytherapy can also be used in the treatment of tumours of the brain, eye, head and neck region (lip, floor of mouth, tongue, nasopharynx and oropharynx), [10] respiratory tract (trachea and bronchi), digestive tract (oesophagus, gall ...
Caesium-137 (137 55 Cs), cesium-137 (US), [7] or radiocaesium, is a radioactive isotope of caesium that is formed as one of the more common fission products by the nuclear fission of uranium-235 and other fissionable isotopes in nuclear reactors and nuclear weapons. Trace quantities also originate from spontaneous fission of uranium-238. It is ...
Due to their short half-lives of 5 and 8 days they have now decayed, leaving the more long-lived 137 Cs (with a half-life of 30.07 years) and 90 Sr (with a half-life of 28.78 years) as main dangers. In March 2011, an earthquake and tsunami caused damage that led to explosions and partial meltdowns at the Fukushima I Nuclear Power Plant in Japan.
Caesium-137 is one such radionuclide. It has a half-life of 30 years, and decays by beta decay without gamma ray emission to a metastable state of barium-137 (137m Ba). Barium-137m has a half-life of a 2.6 minutes and is responsible for all of the gamma ray emission in this decay sequence. The ground state of barium-137 is stable.
Results from a phase 3 clinical trial show promise for a new standard of care for treating people with advanced cervical cancer. The new treatment includes a combination of induction chemotherapy ...
a cylinder of radioactive source material (caesium-137 in the Goiânia incident, but usually cobalt-60) The Goiânia accident [ɡojˈjɐniɐ] was a radioactive contamination accident that occurred on September 13, 1987, in Goiânia , Goiás , Brazil, after an unsecured radiotherapy source was stolen from an abandoned hospital site in the city.
Cervical cancer is the 12th-most common cancer in women in the UK (around 3,100 women were diagnosed with the disease in 2011) and accounts for 1% of cancer deaths (around 920 died in 2012). [152] With a 42% reduction from 1988 to 1997, the NHS-implemented screening programme has been highly successful, screening the highest-risk age group (25 ...
They sold the kilocurie (40 TBq) caesium-137 source as a glowing curiosity. Two hundred and fifty people were contaminated; four died. [27] June 6, 1988 – Radiation Sterilizers, Inc. (now Sterigenics) in Decatur, Georgia reported a leak of 137 Cs at their facility. Seventy thousand medical supply containers and milk cartons were recalled.
