HFC-125 measured by the Advanced Global Atmospheric Gases Experiment in the lower atmosphere (troposphere) at stations around the world. Abundances are given as pollution free monthly mean mole fractions in parts-per-trillion. Atmospheric concentration of pentafluoroethane at various latitudes since year 2007.
Iodine-125 (125 I) is a radioisotope of iodine which has uses in biological assays, nuclear medicine imaging and in radiation therapy as brachytherapy to treat a number of conditions, including prostate cancer, uveal melanomas, and brain tumors. It is the second longest-lived radioisotope of iodine, after iodine-129.
125 I is frequently used in radioimmunoassays because of its relatively long half-life (59 days) and ability to be detected with high sensitivity by gamma counters. [8] 129 I is present in the environment as a result of the testing of nuclear weapons in the atmosphere. It was also produced in the Chernobyl and Fukushima disasters.
There are 37 artificial radioactive isotopes, the longest-lived of which are 125 Sb, with a half-life of 2.75856 years; 124 Sb, with half-life 60.2 days; and 126 Sb, with half-life 12.35 days. All other isotopes have half-lives less than 4 days, most less than an hour.

Alfred Nobel's last will of 1895 only included five prizes, covering outstanding achievements who confer the "greatest benefit on mankind" in the fields of chemistry, physics, literature, peace, and physiology or medicine. The original Nobel prizes thus includes: Nobel Prize in Chemistry; Nobel Prize in Physics; Nobel Prize in Literature
Anki (US: / ˈ ɑː ŋ k i /, UK: / ˈ æ ŋ k i /; Japanese:) is a free and open-source flashcard program. It uses techniques from cognitive science such as active recall testing and spaced repetition to aid the user in memorization.
The following is a list of ammunition fired by the 125 mm smoothbore gun series used in the T-64, T-72, T-80, M-84, T-90, PT-91, T-14 Armata, and other tanks derived from those designs, as well as the 2A45 Sprut anti-tank gun.
