Nuclear decay in general is not predictable
Are constant
Another term for a decay clock is a "radiometric clock." This term refers to methods of measuring time based on the predictable decay rates of radioactive isotopes, which are used in dating geological and archaeological samples.
Nuclear decay rates do not vary with the conditions of the change; they are constant for a given isotope. On the other hand, chemical reaction rates can vary with conditions such as temperature, pressure, and the presence of catalysts.
A decay system refers to a process in which a substance or entity loses its properties, energy, or quantity over time, often in a predictable manner. This concept is commonly applied in various fields, such as physics (radioactive decay), biology (cellular decay), and even economics (depreciation of assets). In these contexts, decay can be characterized by specific rates or half-lives, indicating how quickly the substance diminishes. Understanding decay systems is crucial for modeling changes and predicting future behavior in diverse applications.
Radioactive decay is used to date fossils and artifacts because certain radioactive isotopes have predictable rates of decay over time. By measuring the amount of remaining radioactive isotopes in a fossil or artifact, scientists can estimate how long it has been since the material was formed. This method is known as radiometric dating and provides a way to determine the age of objects that are thousands to billions of years old.
Radiometric dating is possible because the rates of decay of radioactive isotopes are constant and predictable over time. By measuring the amount of remaining parent and daughter isotopes in a sample, scientists can determine the age of the sample.
Radioactive materials decay at predictable rates
Nuclear decay rates vary, but chemical reaction rates are constant
Yes, for any specific isotope they are fixed constant.

If radioactive decay rates were not constant, the passage of time inferred from radiometric dating would be inaccurate. Changes in decay rates would affect the ratio of parent to daughter isotopes used in dating, leading to flawed age calculations. The fundamental assumption of radiometric dating is that decay rates remain constant over time.
Isotopes decay (half-life) at different, predictable rates. Mathematical formulae have been worked out to show how the percentage of decay in known isotopes can date a particular specimen.
In general, a radioactive substance decays at a constant rate throughout time. That is not to say that the same number of decays occur per unit time. They cannot, and this is because the sample is shrinking as radioactive decay "claims" more and more of it. The decays per second is decreasing. But the rate of decay remains constant. There are some instances where slight changes in decay rates of a couple of different radioactive substances occur when we put them in extreme magnetic fields. But, by and large, the decay rates of radionuclides are constant. Additionally, we've gone to great lengths in an attempt to induce changes in the decay rates of a number of radionuclides, but they've proved themselves sublimely resistant to any manipulation by the likes of us, even as clever as we are.

Radiometric dating is possible because radioactive isotopes decay at a predictable rate over time. By measuring the amount of parent and daughter isotopes in a sample, scientists can calculate the age of the material. The rates of decay of radioactive isotopes serve as a reliable clock for determining the age of rocks and fossils.
nuclear decay rates take more time and chemical reaction rates could happen fast.
