Alpha decay (two protons and two neutrons) changes the mass number of the element by -4 and the atomic number by -2 so the remaining nucleus will be \(_{90}^{234}?\). A periodic table shows that ...

Recall that the solution of the initial-value problem \(y^\prime=ky\text{,}\) \(y(0)=A\text{,}\) is given by \(\ds y=Ae^{kx}\text{.}\) Solve the following problems ...

AFTER the exponential law in radioactive decay had been discovered in 1902 ... The peculiar property of the wave mechanical equations which finds application here has also been applied to the ...

Recall that the solution of the initial-value problem \(y^\prime=ky\text{,}\) \(y(0)=A\text{,}\) is given by \(\ds y=Ae^{kx}\text{.}\) Solve the following problems ...

Changes due to radioactive decay can be represented by balanced nuclear equations. The changes that happen depend on the type of radiation emitted.

Certain isotopes are unstable and undergo a process of radioactive decay, slowly and steadily transforming, molecule by molecule, into a different isotope. This rate of decay is constant for a ...

However, if you don’t have one, you can look for yellowed glass. Radioactive decay could also cause hot spots on digital cameras. In the consumer market, it doesn’t look like radioactive ...

A differential equation is an equality constraining a mathematical function in relation to its derivatives over one or multiple variables. Such equations may constitute the mathematical model for ...

Sealed radioactive sources are widely used for beneficial purposes in medicine, industry, and agriculture. A sealed radioactive source is radioactive material that is permanently sealed in a capsule ...

A nuclear battery powered by radioactive decay rather than chemical reactions could last for decades. The most efficient design yet may bring this concept closer to reality. Researchers have ...

The battery developed by the research team at China’s Soochow University harnesses the energy of radioactive decay, a process ...
