  2. Thallium

Alpha decay

Alpha decay or α-decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and thereby transforms or "decays" into a different atomic nucleus, with a mass number that is reduced by four and an atomic number that is reduced by two.

See Isotopes of thallium and Alpha decay

Atomic mass

The atomic mass (ma or m) is the mass of an atom.

See Isotopes of thallium and Atomic mass

Beta decay

In nuclear physics, beta decay (β-decay) is a type of radioactive decay in which an atomic nucleus emits a beta particle (fast energetic electron or positron), transforming into an isobar of that nuclide.

See Isotopes of thallium and Beta decay

Bismuth-209

Bismuth-209 (Bi) is an isotope of bismuth, with the longest known half-life of any radioisotope that undergoes α-decay (alpha decay).

See Isotopes of thallium and Bismuth-209

Cardiac stress test

A cardiac stress test is a cardiological examination that evaluates the cardiovascular system's response to external stress within a controlled clinical setting.

See Isotopes of thallium and Cardiac stress test

Cyclotron

A cyclotron is a type of particle accelerator invented by Ernest Lawrence in 1929–1930 at the University of California, Berkeley, and patented in 1932.

See Isotopes of thallium and Cyclotron

Decay chain

In nuclear science, the decay chain refers to a series of radioactive decays of different radioactive decay products as a sequential series of transformations.

See Isotopes of thallium and Decay chain

Decay product

In nuclear physics, a decay product (also known as a daughter product, daughter isotope, radio-daughter, or daughter nuclide) is the remaining nuclide left over from radioactive decay.

See Isotopes of thallium and Decay product

Electron capture

Electron capture (K-electron capture, also K-capture, or L-electron capture, L-capture) is a process in which the proton-rich nucleus of an electrically neutral atom absorbs an inner atomic electron, usually from the K or L electron shells.

See Isotopes of thallium and Electron capture

Half-life

Half-life (symbol) is the time required for a quantity (of substance) to reduce to half of its initial value.

See Isotopes of thallium and Half-life

International Atomic Energy Agency

The International Atomic Energy Agency (IAEA) is an intergovernmental organization that seeks to promote the peaceful use of nuclear energy and to inhibit its use for any military purpose, including nuclear weapons.

Isotope

Isotopes are distinct nuclear species (or nuclides) of the same chemical element.

See Isotopes of thallium and Isotope

Isotopes of lead

Lead (82Pb) has four observationally stable isotopes: 204Pb, 206Pb, 207Pb, 208Pb. Isotopes of thallium and isotopes of lead are Lists of isotopes by element.

Isotopes of neptunium

Neptunium (93Np) is usually considered an artificial element, although trace quantities are found in nature, so a standard atomic weight cannot be given. Isotopes of thallium and Isotopes of neptunium are Lists of isotopes by element.

Neptunium

Neptunium is a chemical element; it has symbol Np and atomic number 93.

See Isotopes of thallium and Neptunium

Neutron activation

Neutron activation is the process in which neutron radiation induces radioactivity in materials, and occurs when atomic nuclei capture free neutrons, becoming heavier and entering excited states.

See Isotopes of thallium and Neutron activation

Neutron emission

Neutron emission is a mode of radioactive decay in which one or more neutrons are ejected from a nucleus.

See Isotopes of thallium and Neutron emission

Nuclear isomer

A nuclear isomer is a metastable state of an atomic nucleus, in which one or more nucleons (protons or neutrons) occupy excited state (higher energy) levels.

See Isotopes of thallium and Nuclear isomer

Nuclear reactor

A nuclear reactor is a device used to initiate and control a fission nuclear chain reaction or nuclear fusion reactions.

See Isotopes of thallium and Nuclear reactor

Proton emission

Proton emission (also known as proton radioactivity) is a rare type of radioactive decay in which a proton is ejected from a nucleus.

See Isotopes of thallium and Proton emission

Radionuclide

A radionuclide (radioactive nuclide, radioisotope or radioactive isotope) is a nuclide that has excess numbers of either neutrons or protons, giving it excess nuclear energy, and making it unstable.

See Isotopes of thallium and Radionuclide

Radiopharmaceutical

Radiopharmaceuticals, or medicinal radiocompounds, are a group of pharmaceutical drugs containing radioactive isotopes.

See Isotopes of thallium and Radiopharmaceutical

Scintigraphy

Scintigraphy (from Latin scintilla, "spark"), also known as a gamma scan, is a diagnostic test in nuclear medicine, where radioisotopes attached to drugs that travel to a specific organ or tissue (radiopharmaceuticals) are taken internally and the emitted gamma radiation is captured by gamma cameras, which are external detectors that form two-dimensional images in a process similar to the capture of x-ray images.

See Isotopes of thallium and Scintigraphy

Spontaneous fission

Spontaneous fission (SF) is a form of radioactive decay in which a heavy atomic nucleus splits into two or more lighter nuclei.

See Isotopes of thallium and Spontaneous fission

Stable nuclide

Stable nuclides are nuclides that are not radioactive and so (unlike radionuclides) do not spontaneously undergo radioactive decay.

See Isotopes of thallium and Stable nuclide

Synthetic radioisotope

A synthetic radioisotope is a radionuclide that is not found in nature: no natural process or mechanism exists which produces it, or it is so unstable that it decays away in a very short period of time.

See Isotopes of thallium and Synthetic radioisotope

Thallium

Thallium is a chemical element; it has symbol Tl and atomic number 81.

Thorium-232

Thorium-232 is the main naturally occurring isotope of thorium, with a relative abundance of 99.98%.

United States Department of Energy

The United States Department of Energy (DOE) is an executive department of the U.S. federal government that oversees U.S. national energy policy and energy production, the research and development of nuclear power, the military's nuclear weapons program, nuclear reactor production for the United States Navy, energy-related research, and energy conservation.

Uranium-235

Uranium-235 (235U or U-235) is an isotope of uranium making up about 0.72% of natural uranium.

See Isotopes of thallium and Uranium-235

Uranium-238

Uranium-238 (238U or U-238) is the most common isotope of uranium found in nature, with a relative abundance of 99%.
