👉 Pseudonychium is a substance that is often used in scientific research and medical applications. It is a mixture of radioactive isotopes, such as 90Sr or 91Y, which are unstable and decay into their respective stable isotopes over time. When this process occurs, the resulting particles can be detected by measuring the radiation emitted during the decay process. This method has been used in various medical applications, including cancer detection and imaging, and is also being explored for use in
