Many atoms are balanced. Carbon-12, for example, will remain carbon-12 forever. Likewise, a Oksijen16 atom will forever remain a Oksijen16 atom. However, some atoms, such as uranium, do not have decisive cores, and may therefore be completely disintegrated into new atoms. We call these kinds of atoms "unstable" or "radioactive" atoms.
Radiation scattered during radioactive degradation can be in the form of particles such as neutrons, alpha particles and beta particles, or in the form of pure energy, such as gamma and x-rays.
Types of radioactivity
Beta particle; These are electrons that are energized in the core. Beta radiation can penetrate the skin, but can be easily blocked by a thin piece of metal, such as aluminum foil.
Gamma radiation; Photons scattered by the core. Gamma rays are similar to light rays, but they are much more energetic because they have a much higher frequency. It's not loaded, so it can pass through almost anything. For this reason, thick lead or cement walls are required to prevent these beams.
Alpha particle; It consists of two protons and two neutrons that form the helium core. These particles are relatively large and cannot penetrate the material easily. Even thin paper can easily stop alpha flare.
What's a half-life?
When cores are degraded through alpha, beta and gamma degradation, the number of radioactive cores in the sample decreases because they cannot re-enter the same degradation process. The number of radioactive cores in a sample decreases exponentially.The rate of activity or decay is the rate of change in the number of radioactive cores.
The minus sign indicates that the number of radioactive cores in the sample decreases over time. $latex\lambda&s=1 is called an end constant. Returns the possibility of a specific core degradation in unit time. The deterioration constant has a certain value for a specific nuclear degradation process.
