Question
**Question: What type of radiation has a positive charge?** **Options:** - **Alpha particle (α)** - **Beta particle (β)** - **Gamma ray (γ)** - **Delta ray (δ)** **Explanation:** An alpha particle, denoted by the Greek letter α, consists of 2 protons and 2 neutrons bound together into a particle identical to a helium-4 nucleus. It is a type of ionizing radiation with a positive charge. Understanding the different types of radiation is essential in fields such as radiology, nuclear physics, and various medical applications. Here is a brief description of each type listed: 1. **Alpha Particles (α):** These particles are positively charged and relatively heavy compared to other types of radiation. They can be stopped by a paper sheet or even the outer layer of human skin. 2. **Beta Particles (β):** These are high-energy, high-speed electrons or positrons emitted by certain types of radioactive nuclei. They are lighter than alpha particles and have a negative (or positive in the case of positrons) charge. They can penetrate paper but are generally stopped by plastic or a few millimeters of a metal like aluminum. 3. **Gamma Rays (γ):** These are high-frequency electromagnetic waves and do not have any charge. They are highly penetrating and require dense materials like lead or several centimeters of concrete to be effectively blocked. 4. **Delta Rays (δ):** Although not as commonly discussed as alpha, beta, and gamma rays, delta rays generally refer to secondary ionization electrons produced by other high-energy particles passing through a material. Delta rays themselves don't have a distinct charge but are a product of ionizing interactions. In this multiple-choice question, the correct answer is "Alpha particle (α)."
