lämpöseulontaan

Lämpöseulonta, also known as thermal screening, is a non-contact method used to measure human body surface temperature. Its primary purpose is to detect individuals who may have an elevated body temperature, which can be an indicator of a fever. This fever can be a symptom of various illnesses, including infectious diseases.

The technology behind lämpöseulonta typically involves infrared thermography or thermal imaging cameras. These devices detect the infrared radiation emitted by the human body and convert it into a visual representation, often a heatmap, where different colors correspond to different temperature ranges. A person's forehead is commonly targeted as it is a relatively stable and accessible area for measurement.

Lämpöseulonta is often employed in public spaces such as airports, train stations, hospitals, and large events. It serves as a preliminary screening tool to identify individuals who might require further medical assessment. It is important to note that lämpöseulonta is not a diagnostic tool. An elevated temperature detected by thermal screening does not definitively mean a person is ill; factors like environmental conditions or recent physical activity can also influence surface temperature. Those identified with a higher temperature are usually directed to a more precise measurement device, such as a medical thermometer, for confirmation and further evaluation by healthcare professionals. The widespread use of lämpöseulonta increased significantly during the COVID-19 pandemic as a measure to help mitigate the spread of the virus.
