One of the first things that Physics students learn when they study radioactivity is the idea of the half-life. A half-life is the period of time in which it takes one-half of a given amount of a ...

To understand nuclear decay equations. How to measure the activity of radioactive sources. Spontaneously means that the process of radioactive decay can not be speeded up or slowed down by physical ...

Radioactive decay is the strange and almost mystical ability for one element to naturally and spontaneously transmute into another. In the process, those elements tend to emit deadly forms of ...

Radioactive material gets a bad rap, what with radiation and fallout and nuclear waste and all. But it offers some practical uses. One of the coolest (OK, maybe the coolest) is using radioactive ...

Researchers refute the assumption that the decay rate of some radioactive nuclides depends on the distance between the Earth and the Sun. PTB researchers refute the assumption that the decay rate of ...

Figure 1: The conventional PET tracer principle and the development of agents that fluorescently convert the Cerenkov radiation optical decay signal. Here, we describe a new imaging strategy, ...

Imagine a battery that doesn’t need replacing for thousands of years. That’s not science fiction—it’s the groundbreaking innovation that a group of researchers in the UK has recently achieved. By ...
