BODY SCANNER Meaning and
Definition
-
A body scanner is a comprehensive security device designed to detect concealed objects or substances on or within a person's body. It is primarily used in security checkpoints at airports, correctional facilities, high-security government buildings, and other locations where enhanced security measures are required.
Typically, a body scanner utilizes advanced imaging technology to create a detailed outline image of a person's body. The system emits either X-rays or millimeter-wave radio waves, both of which are harmless in small doses, and captures the resulting reflections or transmissions. These waves or rays easily penetrate clothing but may be blocked by solid or dense objects.
The captured images are processed by the scanner's software algorithms, which analyze the data and alert security personnel of any potential threats or anomalies. This allows security officers to identify hidden items such as weapons, explosives, or illicit substances that an individual may be attempting to smuggle or conceal.
Body scanners can be categorized into two main types: X-ray scanners and millimeter-wave scanners. X-ray scanners use low-power X-rays, which produce detailed images of the body's interior. On the other hand, millimeter-wave scanners utilize radio waves to generate a three-dimensional image of the body's surface, highlighting any objects or irregularities.
The use of body scanners has significantly enhanced security measures, providing a non-invasive method of screening individuals while maintaining their privacy. It has become an essential component of modern security protocols, aiding in the prevention of potential threats and ensuring the safety of individuals and facilities.

Etymology of BODY SCANNER
The word "body scanner" is composed of two parts: "body" and "scanner".
1. Body: "body" comes from the Old English word "bodig" or "bodi", which referred to the physical structure of a living organism. It has Indo-European roots and is related to words in other Germanic languages, such as German "Körper" and Dutch "lichaam". Over time, the word "body" has evolved to encompass the entire physical framework, including the human physique.
2. Scanner: The word "scanner" originated from the Middle English word "scanne" and was derived from Old French "escanner". It came from the Late Latin word "scannāre", which means "to analyze" or "to survey". The Latin term itself may have been influenced by the Greek word "skánnaō", meaning "to examine" or "look at".
