What is the nuclear decay equation for cesium-137?

Answer 1

The equation for the beta decay of 60Co is: 2760Co --> 2860Ni + -10e

where the -10e is a negative beta particle or electron.

Answer 2

The equation for the alpha decay of 235U is:

92235U --> 90231Th + 24He

representing the alpha particle as a helium nucleus.

235U also decays by spontaneous fission, but the results are somewhat unpredictable, so there is no standard equation.

Answer 3

The equation for the beta decay of 14C:614C --> 714N + -10e

and the equation for the beta decay of 90Sr:3890Sr --> 3990Y + -10e

where in both cases the e is an electron or negative beta particle.

Answer 4

When living things (animals & plants) are alive they have the radioactive chemical carbon 14 in their bodies. Radioactive materials emit radiation. When it dies the carbon 14 ceases to be renewed and slowly begins to emit less and less radiation. That is, the radiation decays and it decays at a known rate. So by measuring the amount of radiation being emitted by something long dead scientists can tell how long ago it died.

Answer 5

The equation for the beta decay of 14C: 614C --> 714N + -10e

where the e is an electron.

Answer 6

The equation for the alpha beta decay of 238U is:92238U --> 90234Th + 24He

Where He represents the alpha particle, which can also be viewed as a Helium nucleus.

Answer 7

The equation for the beta decay of 60Co is: 2760Co --> 2860Ni + -10e

where the -10e is a negative beta particle or electron.

Answer 8

The equation for the beta decay of 137Cs is: 55137Cs --> 56137Ba + -10e

where the -10e is a negative beta particle or electron.

Answer 9

713N -> 613C + e+ + ve
