238 Puは、半減期が87.7年の比較的寿命の短い放射性同位体である。これはプルトニウムの同位体の中で5番目に半減期の長いものである 。 238 Puはそのほぼ100%がアルファ崩壊によって崩壊し、 234 Uになる。しかし、低確率ではあるが他の崩壊モードもある。

Sydämentahdistin on kehoon leikkauksella asetettava laite, joka säätelee sydämenlyöntien tahtia. Sydämentahdistinta käytetään rytmihäiriöiden hoidossa, kun potilaan sydämen luonnollinen tahdistus ei ole riittävän nopea tai kun sydämen sähkönjohtavuus on alentunut niin, ettei luonnollinen tahdistus saavuta alempia kammioita.

Plutonium is nearly 20 times denser than water; Pu-238, its isotope used in space exploration, is almost 10 times denser than water. En pacemaker är en liten apparat som hjälper hjärtat att hålla en jämn rytm. Återkommande yrselattacker eller svimningsanfall är en vanlig orsak till att få en pacemaker inopererad. Besvären beror på för långa pauser mellan hjärtslagen. 2020-07-29 * Nuclear fuel for nuclear power reactors (Pu-239 and Pu-241 are fissile isotopes) * Nuclear weapons * Power and thermal sources - Pu-238 (for pacemakers, spacecrafts, etc.) * Neutron source, as Pu-Be In 1970, The First Heart Pacemaker Powered By A Nuclear Battery Was Implanted In A Patient.4 The Pacemaker Was Designed And Built By Medtronic; Its Nuclear Bat- Tery Was Manufactured By Alcatel, And Contained A 2.5-Ci Metallic Pu-238 Source.

Plutonium-238 is a radioactive isotope of Pu, with special characteristics that make it extremely useful, particularly for space exploration. Chemical Structure. Plutonium is nearly 20 times denser than water; Pu-238, its isotope used in space exploration, is almost 10 times denser than water. Here you may find Pu! But this element-238 doesn't stink--it powers pacemakers Jeopardy Answer Current Production of Pu-238. As a result of these findings, NASA decided to invest and resume Pu-238 production.

Notre Commissariat à l'énergie atomique (CEA) eut à un moment un éclair de génie: doter le stimulateur cardiaque d'un générateur au plutonium 238. Plutonium (Pu) is a silvery-white metal. Plutonium-238 is a radioactive isotope of Pu, with special characteristics that make it extremely useful, particularly for space exploration. Chemical Structure.

The thermoelectric generator used Pu-238. Due to the extremely high risk and toxicity involved with using plutonium, numerous layers and shields were woven into these pacemakers resulting in larger and heavier devices. Plutonium in radioisotopic thermal generators is always Plutonium-238 with a 87.7 year half-life. You can't make bombs out of it. The fissile isotopes of Plutonium are 239 (24,000 year half-life) and 241 (14 year half-life, but a beta emitter instead of alpha). Plutonium-238 is an α emitter used to power batteries for heart pacemakers.
