Ionizing radiation has enough energy to remove tightly bound electrons from atoms, creating ions. This type of radiation includes X-rays, gamma rays, and some forms of ultraviolet radiation. Non-ionizing radiation, on the other hand, does not have enough energy to remove electrons from atoms, and includes forms of radiation such as visible light, radio waves, and microwaves. The main difference between the two is the amount of energy they carry and their ability to ionize atoms. **

Ionizing radiation was discovered by Wilhelm Conrad Roentgen in 1895. While experimenting with cathode rays, he noticed that a fluorescent screen in his lab would glow even when it was not directly in the path of the rays. This led him to the discovery of X-rays, which are a form of ionizing radiation. Roentgen's discovery revolutionized the field of medicine and earned him the first Nobel Prize in Physics in 1901. **

Ionizing radiation occurs when an atom undergoes a process that causes it to lose or gain electrons, resulting in the formation of charged particles called ions. This can happen through natural processes such as radioactive decay of certain elements, or through human activities such as medical imaging and nuclear power generation. Ionizing radiation is harmful to living organisms because it can damage cells and DNA, leading to potential health risks such as cancer and genetic mutations. **

Professions that involve working with ionizing radiation include radiologic technologists, nuclear medicine technologists, radiation therapists, and radiologists. These professionals use ionizing radiation in various medical imaging and treatment procedures. Other professions that may involve working with ionizing radiation include nuclear engineers, physicists, and researchers in the field of nuclear energy. **

Different types of ionizing radiation occur in various situations. For example, alpha radiation occurs during the decay of heavy elements such as uranium or radium. Beta radiation occurs during the decay of certain unstable isotopes, while gamma radiation is emitted during nuclear reactions and radioactive decay. X-rays are produced during high-energy processes such as in medical imaging or industrial applications. Each type of ionizing radiation has its own specific source and characteristics. **

Yes, beta-plus radiation belongs to ionizing radiation. Beta-plus radiation consists of positrons, which are positively charged particles that have the ability to ionize atoms by knocking off electrons from their orbits. This process can lead to the formation of charged particles and free radicals, which can cause damage to biological tissues and DNA. Therefore, beta-plus radiation is considered a form of ionizing radiation due to its ability to ionize atoms and cause biological damage. **

TV and radio stations are not legally obligated to broadcast news, but many choose to do so as part of their commitment to serving the public interest. In some countries, there may be regulations or licensing requirements that mandate a certain amount of news programming, but this varies by jurisdiction. Ultimately, the decision to include news in their programming is up to the individual stations and their management. **

Professions that deal with ionizing radiation include radiologic technologists, radiation therapists, nuclear medicine technologists, radiologists, medical physicists, and nuclear engineers. These professionals work in various settings such as hospitals, diagnostic imaging centers, research facilities, and nuclear power plants. They are trained to safely handle and use ionizing radiation for medical diagnosis and treatment, as well as for industrial and energy production purposes. **
