5. What is Radioactive Decay and How Does it Relate to Radiation Travel?

Radioactive decay is the process by which unstable atoms release energy in the form of radiation to become more stable. This radiation travels in the forms of alpha, beta, or gamma rays. The type of decay and the energy released affect how far the radiation travels and its potential impact.

5.1. What Happens During Radioactive Decay?

During radioactive decay, an unstable atom’s nucleus spontaneously transforms, emitting particles and energy to reach a more stable state. This process changes the atom’s identity, creating a new element or isotope.

• Emission of Particles: Radioactive decay often involves the emission of particles, such as alpha particles (two protons and two neutrons), beta particles (electrons or positrons), or neutrons. These particles carry energy away from the nucleus and can interact with surrounding matter.
• Energy Release: Radioactive decay also releases energy in the form of electromagnetic radiation, such as gamma rays or X-rays. This energy is emitted as photons, which are massless particles that travel at the speed of light.
• Change in Atomic Number and Mass Number: Radioactive decay can change the atomic number (number of protons) and mass number (number of protons and neutrons) of the atom. For example, alpha decay decreases the atomic number by 2 and the mass number by 4, while beta decay increases the atomic number by 1 and leaves the mass number unchanged.
• Formation of a New Element or Isotope: As a result of the changes in atomic number and mass number, radioactive decay transforms the original atom into a new element or isotope. This new element or isotope may also be radioactive, leading to a chain of radioactive decays until a stable isotope is formed.

5.2. How Does the Type of Decay Affect Radiation Travel?

The type of particle emitted during decay determines its range and penetration. Alpha particles are heavy and travel short distances, beta particles travel farther, and gamma rays are highly penetrating.

• Alpha Decay: Alpha particles are relatively heavy and carry a large positive charge, so they interact strongly with matter and lose energy quickly. As a result, they have a short range and can be stopped by a sheet of paper or the outer layer of skin.
• Beta Decay: Beta particles are lighter and carry a smaller charge than alpha particles, so they interact less strongly with matter and travel farther. They can penetrate several millimeters of skin or a thin sheet of aluminum.
• Gamma Decay: Gamma rays are high-energy photons that have no mass or charge, so they interact very weakly with matter and travel long distances. They can penetrate through several inches of lead or several feet of concrete.

5.3. What are Radionuclides and Their Role in Radioactive Decay?

Radionuclides are unstable atoms that undergo radioactive decay, emitting radiation. They are found naturally in the environment and are also produced in nuclear reactors and other facilities.

• Natural Radionuclides: Natural radionuclides are present in the environment due to their formation in the early universe or through ongoing natural processes. Examples include uranium-238, thorium-232, and potassium-40.
• Artificial Radionuclides: Artificial radionuclides are produced in nuclear reactors, particle accelerators, or through nuclear weapons testing. Examples include cesium-137, strontium-90, and iodine-131.
• Decay Chains: Radionuclides often undergo a series of radioactive decays, forming a chain of radioactive isotopes until a stable isotope is reached. The decay chain for uranium-238, for example, includes several intermediate radionuclides before ending with stable lead-206.
• Half-Life: Radionuclides have a characteristic half-life, which is the time it takes for half of the atoms in a sample to decay. Half-lives range from fractions of a second to billions of years, depending on the radionuclide.
