Indium-111 (111 In) is a radioactive isotope of indium (In). It decays by electron capture to stable cadmium-111 with a half-life of 2.8 days. [3] Indium-111 chloride (111 InCl) solution is produced by proton irradiation of a cadmium target (112 Cd(p,2n) or 111 Cd(p,n)) in a cyclotron, as recommended by International Atomic Energy Agency (IAEA).

Indium (49 In) consists of two primordial nuclides, with the most common (~ 95.7%) nuclide (115 In) being measurably though weakly radioactive. Its spin-forbidden decay has a half-life of 4.41×10 14 years, much longer than the currently accepted age of the Universe. The stable isotope 113 In is only 4.3% of
Stable even–even nuclides number as many as three isobars for some mass numbers, and up to seven isotopes for some atomic numbers. Conversely, of the 251 known stable nuclides, only five have both an odd number of protons and odd number of neutrons: hydrogen-2 , lithium-6, boron-10, nitrogen-14, and tantalum-180m.
Indium has 39 known isotopes, ranging in mass number from 97 to 135. Only two isotopes occur naturally as primordial nuclides: indium-113, the only stable isotope, and indium-115, which has a half-life of 4.41 × 10 14 years, four orders of magnitude greater than the age of the Universe and nearly 30,000 times greater than half life of thorium ...

TV 6 analog audio can be heard on FM 87.75 on most broadcast radio receivers as well as on a European TV tuned to channel 4A or channel C, but at lower volume than wideband FM broadcast stations, because of the lower deviation. Channel 1 audio is the same as European Channel 2 audio and the video is the same as European Channel 2A.
The darker more stable isotope region departs from the line of protons (Z) = neutrons (N), as the element number Z becomes larger. ... indium: 1: 1: 115 In: 113 In: 57:
The two natural radioactive isotopes are 113 Cd (beta decay, half-life is 8.04 × 10 15 years) and 116 Cd (two-neutrino double beta decay, half-life is 2.8 × 10 19 years). The other three are 106 Cd, 108 Cd ( double electron capture ), and 114 Cd (double beta decay); only lower limits on their half-life times have been set.
