Description : The maximum biological damage is produced by – (1) X rays (2) gamma - rays (3) beta - rays (4) alpha - rays
Last Answer : (2) gamma - rays Explanation: Gamma radiation, also known as gamma rays, is electromagnetic radiation of high frequency and therefore high energy. Gamma rays are ionizing radiation and are thus biologically hazardous.
Description : The radiation initially produced in fluorescent tube is – (1) infrared (2) ultraviolet (3) microwaves (4) X-rays
Last Answer : (2) ultraviolet Explanation: The primary radiation that is initially produced within a fluorescent lamp is analogous to that emitted by a low pressure mercury lamp. Fluorescent lamps produce UV radiation by ... coating on the inside of the tubes absorbs the UV and converts it to visible light.
