2. Isotopes of copper - Wikipedia

   en.wikipedia.org/wiki/Isotopes_of_copper

   Copper (29 Cu) has two stable isotopes, 63 Cu and 65 Cu, along with 28 radioisotopes. The most stable radioisotope is 67 Cu with a half-life of 61.83 hours. Most of the others have half-lives under a minute. Unstable copper isotopes with atomic masses below 63 tend to undergo β + decay, while isotopes with atomic masses above 65 tend to ...

3. Copper foil - Wikipedia

   en.wikipedia.org/wiki/Copper_foil

   Copper foil is a thin sheet of copper metal that is widely used in various applications due to its excellent electrical conductivity, malleability, and corrosion resistance. It is an essential material in the electronics industry, especially for manufacturing printed circuit boards (PCBs) and other electronic components.

4. Copper–tungsten - Wikipedia

   en.wikipedia.org/wiki/Copper–tungsten

   The mixture with less wt.% of copper has higher density, higher hardness, and higher resistivity. The typical density of CuW90, with 10% of copper, is 16.75 g/cm 3 and 11.85 g/cm 3 for CuW50 . CuW90 has higher hardness and resistivity of 260 HB kgf/mm 2 and 6.5 μΩ.cm than CuW50. Typical properties of commonly used copper tungsten compositions [1]

5. Copper-64 - Wikipedia

   en.wikipedia.org/wiki/Copper-64

   Copper-64 (64 Cu) is a positron and beta emitting isotope of copper, with applications for molecular radiotherapy and positron emission tomography. Its unusually long half-life (12.7-hours) for a positron-emitting isotope makes it increasingly useful when attached to various ligands , for PET and PET-CT scanning.

6. Radiometric dating - Wikipedia

   en.wikipedia.org/wiki/Radiometric_dating

   Radiometric dating, radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon, ...

7. Cookware and bakeware - Wikipedia

   en.wikipedia.org/wiki/Cookware_and_bakeware

   Pots and pans are cold-formed from copper sheets of various thicknesses, with those in excess of 2.5 mm considered commercial (or extra-fort) grade. Between 1 mm and 2.5 mm wall thickness is considered utility ( fort ) grade, with thicknesses below 1.5 mm often requiring tube beading or edge rolling for reinforcement.

8. Radioactive tracer - Wikipedia

   en.wikipedia.org/wiki/Radioactive_tracer

   Radioisotopes of hydrogen, carbon, phosphorus, sulfur, and iodine have been used extensively to trace the path of biochemical reactions. A radioactive tracer can also be used to track the distribution of a substance within a natural system such as a cell or tissue , [ 1 ] or as a flow tracer to track fluid flow .

9. Food irradiation - Wikipedia

   en.wikipedia.org/wiki/Food_irradiation

   The international Radura logo, used to show a food has been treated with ionizing radiation. A portable, trailer-mounted food irradiation machine, c. 1968 Food irradiation (sometimes American English: radurization; British English: radurisation) is the process of exposing food and food packaging to ionizing radiation, such as from gamma rays, x-rays, or electron beams.
