TīmeklisThe mathematical expression that relates radioactive decay to geologic time is called the age equation and is: t=1/delta ln (1 + D/P) where: t is the age of a rock or mineral specimen, D is the number of atoms of a daughter product today, P is the number of atoms of the parent product today, ln s the natural logarithm (logarithm to base e), and. TīmeklisThe unstable or more commonly known radioactive isotopes break down by radioactive decay into other isotopes. Radioactive decay is a natural process and comes from the atomic nucleus becoming unstable and releasing bits and pieces. These are released as radioactive particles (there are many types). ...
Tīmeklis44. Possible answer: During fission, a larger nucleus is broken down into two smaller nuclei. During fusion, a larger nucleus is formed from smaller nuclei. Fission … Tīmeklis2014. gada 3. sept. · Rubidium-87 is radioactive and decays to stable 87 Sr:-. 87 Rb → 87 Sr + β¯ + ⊽ + Q. A negative β-particle (β¯) and an anti-neutrino (⊽) are both emitted in this process. The decay energy ( Q) is shared as kinetic energy by these two particles. Fortunately this β-decay of 87 Rb is a single-step process.

Chemical properties: I-131 can change directly from a solid into a gas, skipping the liquid phase, in a process called sublimation. I-131 dissolves easily in water or alcohol. I-131 readily combines with other elements and does not stay in its pure form once released into the environment. paliativo paciente
