  • shutdowns
  • Some 50,000 Americans each day depend on a strange and precarious supply chain easily disrupted by a variety of menaces: shipments grounded by fog in Dubai, skittish commercial airline pilots who refuse to carry radioactive material and unplanned nuclear reactor shutdowns, including one in South Africa when a mischievous baboon sneaked into a reactor hall.

  • sodium
  • 2. The use of two tracers permits differentiation between the unabsorbed orally administered sodium in the stools and the sodium which has been absorbed and resecreted. (clinsci.org)
  • protein
  • This study was designed to examine the feasibility of combining lymphoscintigraphy and intraoperative sentinel node identification in patients with head and neck melanoma by using a hybrid protein colloid that is both radioactive and fluorescent. (pubmedcentralcanada.ca)
  • Malaba L, Kindberg GM, Norum KR, Berg T and Blomhoff R (1993) Receptorā€mediated endocytosis of retinolā€binding protein by liver parenchymal cells: interference by radioactive iodination. (els.net)
  • Studies
  • A portable gamma camera was introduced with a better spatial resolution than the probe, and initial studies showed promising results in the intraoperative visualization of radioactive sentinel nodes, but this device cannot depict the surrounding anatomy. (pubmedcentralcanada.ca)
  • Study
  • But the same hilarious bit of mass poisoning could also be used to study the life-cycle of human fat cells, by literally measuring how radioactive people's asses were . (cracked.com)
  • cells
  • Using the PET scanner, it is possible to see how the tracer is taken up by and distributed within cells or organs. (agingpharma.org)
  • Radioactive compounds are incorporated into cells in the same way as their nonradioactive counterparts. (britannica.com)
  • One great way to do this in test animals is to feed them irradiated food, which contains a specific radioactive marker called carbon-14, and then count how the irradiated fat cells appear and degrade over time. (cracked.com)
  • least
  • It became absorbed into plants, animals, and basically every other part of the food chain, and if you were alive at the time, you were at least a little bit radioactive. (cracked.com)
  • At least 1,000 radioactive isotopes occur in nature or have been produced synthetically in particle accelerators (atom-smashers) or nuclear reactors (devices used to control the release of energy from nuclear reactions). (encyclopedia.com)
