The Half-life Period of a Radioactive Substance Depends Upon

Why Half-life Period is Depends Upon Nature of Sample

• Half-life: The period of time during which half of a substance decays is referred to as the substance’s half-life.
• The decay constant is the likelihood of radioactive material decomposing per unit of time.

Half-life (t1/2) = ln2/λ

• In a first-order process, the half-life typically depends on temperature and pressure, however in the case of radioactivity, the half-life is only little affected by temperature and pressure changes. We therefore presume that it is unaffected by both pressure and temperature.
• Furthermore, because it is a feature of radioactive material, the radioactive decay constant is not affected by temperature or pressure.
• It is solely based on the characteristics of the radioactive sample.
• For any first-order reaction, the radioactive constant is temperature and pressure-dependent, but in the unique instance of radioactivity, the decay constant is temperature and pressure-independent.

Summary:-

The Half-life Period of a Radioactive Substance Depends Upon- Temperature, Pressure, Nature of sample, None of the above

In a radioactive material, the half life period depends upon the nature of sample. Since the decay constant and half-life are inversely related the sample type affects the half-life of radioactive material.
