These problems address the derivation of equations, determination of concentration and purity through kinetics experiments, understanding enzyme mechanisms and inhibition, and isotopic tracer analysis. Additional concepts include rate calculations, enzyme activity, flow injection analysis, standard deviation, and competitive inhibitor effects.

For many analytes, however, we can induce radioactivity by irradiating the sample with neutrons in a process called neutron activation analysis (NAA). The radioactive element formed by neutron activation decays to a stable isotope by emitting a gamma ray, and, possibly, other nuclear particles.

Although an element’s different isotopes have the same chemical properties, their nuclear properties are different. The most important difference between isotopes is their stability. The nuclear configuration of a stable isotope remains constant with time. Unstable isotopes, however, spontaneously disintegrate, emitting radioactive particles as they transform into a more stable form.

Unlike many other analytical techniques, NAA is based on nuclear rather than electronic transitions. In NAA, samples are subjected to neutron radiation (i.e., bombarded with neutrons), which causes the elements in the sample to capture free neutrons and form radioactive isotopes.

It describes the types of radioactive decay particles (alpha, beta, gamma rays, and X-rays) and the role of isotopes in identifying nuclear stability. It also covers the mathematical models for radioactive decay, including first-order kinetics and half-life calculations.
