which the human eye can't perceive is broken down into four categories depending on wavelength and photon energy.
These rare types of melanoma are not usually influenced by ultraviolet radiation
in the same way as skin melanoma and are often detected at a more advanced stage due to their locations.
Exposure to ultraviolet radiation
starts a chain reaction of events that ends in either prematurely aged skin, skin cancer, or both.
Melanoma, the most dangerous form of skin cancer, is most often caused by ultraviolet radiation
from sunshine or tanning beds.
The observed amount of ultraviolet radiation
emitted by TRAPPIST-1 indeed suggests that the planets could have lost gigantic amounts of water over the course of their history.
In tungsten-halogen lamps manufactured with a standard fused silica quartz capsule, the quartz absorbs little of the ultraviolet radiation
above 200 nanometers.
The first FOV (FOV1) is used to observe the stars which is called star sensor, and another FOV (FOV2) is used to observe ultraviolet radiation
of the earth which is called ultraviolet earth sensor.
Environmental constraints on spawning depth of yellow perch: The roles of low temperature and high solar ultraviolet radiation
A MEDIUM-sized asteroid plunging into the ocean would destroy much of the ozone layer, leaving the Earth exposed to dangerous levels of ultraviolet radiation
, it has been claimed.
Scientists have warned that a medium-sized asteroid plunging into the ocean would destroy much of the ozone layer, leaving the Earth exposed to dangerous levels of ultraviolet radiation
Hiding out under a beach umbrella may offer you far less protection from the sun's harmful ultraviolet radiation
than you expect, according to a new study by Spanish researchers.
Women who live in areas that receive more ultraviolet radiation
from the sun are more likely to develop a specific form of an autoimmune disease called dermatomyositis, according to a study published in the August 2009 issues of Arthritis & Rheumatism.
