There also exist 23 metastable excited states.Thermal ionization: Thermal ionization, also known as surface ionization or contact ionization, is a physical process whereby the atoms are desorbed from a hot surface, and in the process are spontaneously ionized.Avid Radiopharmaceuticals: Avid Radiopharmaceuticals is an American company, founded by Dr. Daniel Skovronsky, and based at the University City Science Center research campus in Philadelphia, Pennsylvania.TriiodideIodophor: An Iodophor is a preparation containing iodine complexed with a solubilizing agent, such as a surfactant or povidone (forming povidone-iodine). The result is a water-soluble material that releases free iodine when in solution.Lutetium(III) oxideRhenium pentachlorideThyrotropic cellSamarium(III) chlorideScintillation proximity assay: Scintillation proximity assay (SPA) is an assay development and biochemical screening that permits the rapid and sensitive measurement of a broad range of biological processes in a homogeneous system. The type of beads that are involved in the SPA are microscopic in size and within the beads itself, there is a scintillant which emits light when it is stimulated.Isotopes of calcium: Calcium (Ca) has 24 isotopes, from 34Ca to 57Ca. There are five stable isotopes (40Ca, 42Ca, 43Ca, 44Ca and 46Ca), plus one isotope (48Ca) with such a long half-life that for all practical purposes it can be considered stable.High-level radioactive waste management: High-level radioactive waste management concerns management and disposal of highly radioactive materials created during production of nuclear power and nuclear weapons. Radioactive waste contains a mixture of short-lived and long-lived nuclides, as well as non-radioactive nuclides.Congenital hypothyroidismRhodolithThyroglobulin: Thyroglobulin (Tg) is a 660 kDa, dimeric protein produced by the follicular cells of the thyroid and used entirely within the thyroid gland. Thyroglobulin protein accounts for approximately half of the protein content of the thyroid gland.Alpha particleAffibody molecule: Affibody molecules are small proteins engineered to bind to a large number of target proteins or peptides with high affinity, imitating monoclonal antibodies, and are therefore a member of the family of antibody mimetics. Affibody molecules are used in biochemical research and are being developed as potential new biopharmaceutical drugs.Sodium pertechnetateAldehyde ferredoxin oxidoreductase: In enzymology, an aldehyde ferredoxin oxidoreductase () is an enzyme that catalyzes the chemical reactionIsotopes of meitnerium: Meitnerium (Mt) is a synthetic element, and thus a standard atomic mass cannot be given. Like all synthetic elements, it has no stable isotopes.Cobalt therapy: Cobalt therapy or cobalt-60 therapy is the medical use of gamma rays from the radioisotope cobalt-60 to treat conditions such as cancer. Beginning in the 1950s cobalt-60 was widely used in external beam radiotherapy (teletherapy) machines, which produced a beam of gamma rays which was directed into the patient's body to kill tumor tissue.HypothyroidismFull-spectrum photographyNuclear medicine in Pakistan: The history of pursuing nuclear medicine goes back to 1956, when the Pakistan Atomic Energy Commission (PAEC) was established under the executive order of the Prime Minister of Pakistan, Huseyn Shaheed Suhrawardy. The PAEC, the scientific body who is responsible for establishing the nuclear power plants in the country, has sat up a Nuclear Medicines laboratory.Irradiance: In radiometry (measurement of electromagnetic radiation), irradiance is the radiant flux (power) received by a surface per unit area, and spectral irradiance is the irradiance of a surface per unit frequency or wavelength, depending on whether the spectrum is taken as a function of frequency or of wavelength. The SI unit of irradiance is the watt per square metre (), while that of spectral irradiance is the watt per square metre per hertz (W·m−2·Hz−1) or the watt per square metre per metre (W·m−3)—commonly the watt per square metre per nanometre ().Thyroid hormone: The thyroid hormones, triiodothyronine (T3) and its prohormone, thyroxine (T4), are tyrosine-based hormones produced by the thyroid gland that are primarily responsible for regulation of metabolism. T3 and T4 are partially composed of iodine (see molecular model).FuchsineAutomatic exposure control: Automatic Exposure Control (AEC) is an X-ray exposure termination device. A medical radiography x-ray exposure is always initiated by a human operator.Tritium illumination: Tritium illumination is the use of gaseous tritium, a radioactive isotope of hydrogen, to create visible light. Tritium emits electrons through beta decay, and, when they interact with a phosphor material, fluorescent light is created, a process called radioluminescence.HyperthyroidismNostoc communeIodothyronine deiodinase: Iodothyronine deiodinases ( and ) are a subfamily of deiodinase enzymes important in the activation and deactivation of thyroid hormones. Thyroxine (T4), the precursor of 3,5,3’-triiodothyronine (T3) is transformed into T3 by deiodinase activity.Sodium perchlorateSteptoean positive carbon isotope excursion: The Steptoean Positive Carbon Isotope Excursion (SPICE) was a geological event which occurred about 500 million years ago at the end of the Cambrian Period. The SPICE event was a sudden reversal of the anoxia (lack of oxygen) that had steadily spread throughout the oceans during the Cambrian which also affected the atmosphere.DiiodotyrosineThyroid cancerBrain positron emission tomography: Positron emission tomography (PET) measures emissions from radioactively labeled metabolically active chemicals that have been injected into the bloodstream. The emission data are computer-processed to produce multi-dimensional images of the distribution of the chemicals throughout the brain.
