Types of Packing Materials: The simple packaging materials used in garment and related items are paper, plastic, film, wood, nails, staples, cords, gum tape and metal bands. 1. Wood cases and crates are generally used as packing materials for bulk exports or rugged shipments where shipment handling is higher. 2.

There are four major types of radiation: alpha, beta, neutrons, and electromagnetic waves such as gamma rays. They differ in mass, energy and how deeply they penetrate people and objects. ... Tritium, which is produced by cosmic radiation in the atmosphere and exists all around us, emits beta radiation.

There are three primary means of reducing the radiation dose from sources external to the body: time, distance, and shielding. For a given source of radiation, the amount of radiation energy deposited in the body is related to how long one is exposed.
