This is a list of radioactive nuclides (sometimes also called isotopes), ordered by half-life from shortest to longest, in seconds, minutes, hours, days and years. Current methods make it difficult to measure half-lives between approximately 10 −19 and 10 −10 seconds.
The high short-term radioactivity of spent nuclear fuel is primarily from fission products with short half-life.The radioactivity in the fission product mixture is mostly due to short-lived isotopes such as 131 I and 140 Ba, after about four months 141 Ce, 95 Zr/ 95 Nb and 89 Sr constitute the largest contributors, while after about two or three years the largest share is taken by 144 Ce/ 144 ...
The New York Film Festival (NYFF) is a film festival held every fall in New York City, presented by Film at Lincoln Center. Founded in 1963 by Richard Roud and Amos Vogel with the support of Lincoln Center president William Schuman , NYFF is one of the longest-running and most prestigious film festivals in the United States.

The longest-lived radioisotope is 14 C, with a half-life of 5.70(3) × 10 3 years. This is also the only carbon radioisotope found in nature, as trace quantities are formed cosmogenically by the reaction 14 N + n → 14 C + 1 H. The most stable artificial radioisotope is 11 C, which has a half-life of 20.3402(53) min. All other radioisotopes ...
The 2024 version of NYFF ran from Sept. 27 to Oct. 14 with thousands of cinephiles watching over 100 movies programed by the team at Film at Lincoln Center. The New York Film Festival is set apart ...
have also been characterized, all short-lived. The longest-lived radioisotope is 15 O with a half-life of 122.266(43) s, while the shortest-lived isotope is the unbound 11 O with a half-life of 198(12) yoctoseconds, though half-lives have not been measured for the unbound heavy isotopes 27 O and 28 O.

The 60th New York Film Festival took place from September 30 to October 16, 2022. [1] The opening and closing films of the festival were Noah Baumbach's absurdist comedy-drama White Noise and Elegance Bratton's drama film The Inspection respectively. Laura Poitras' documentary All the Beauty and the Bloodshed was chosen as the center piece film.
New York based distributor Several Futures has acquired Pierre Creton and Vincent Barré’s “7 Walks With Mark Brown” which just had its U.S. premiere at the New York Film Festival. The ...
