No. But you can shield the emitted readiations by absorbers. A well-known shield used for this prupose is lead. If you get your teeth x-rayed at the dentist, you know what this looks like.
Radiation therapy uses radiation from radioactive elements to destroy cancer cells. It works on the principle that cancer cells are more active than normal cells and more prone to radiation damage than normal cells.
Radioactive elements are atoms that are unstable and undergo a process called radioactive decay, where they release energy in the form of radiation. This radiation can take various forms such as alpha particles, beta particles, and gamma rays, and can be harmful to living organisms if exposure occurs.
Photobiologically Active Radiation
Active radiation refers to electromagnetic radiation that carries sufficient energy to ionize atoms or molecules, such as X-rays and gamma rays. This form of radiation can cause damage to living tissue and is used in various applications such as medical imaging and cancer treatment. It is important to handle active radiation with caution and use proper safety measures.
the unstable elements in periodic table is Radium because it always leave the radio active waves so it lost its mass slowly slowly all radio active elements are unstable. Any thing more By Varun
the group1 elements
Metals in group one are chemically active as compared to the elements in group three and two. Elements like sodium, potassium, chlorine and fluorine are some of the chemically active elements.
Capacitors and inductors are considered passive elements, not active elements, because capacitors and inductors do not supply or amplify energy. An example of an active element is a battery, which supplies energy to a circuit.
No.
Fluorine
No. Au (gold) is one of the least active elements.
Radiation is emitted when unstable atoms undergo radioactive decay, releasing energy in the form of particles or electromagnetic waves. This process can occur naturally in certain elements or as a result of human activities, such as in medical procedures or nuclear reactions. The emitted radiation can be in the form of alpha particles, beta particles, gamma rays, or X-rays.
