Ozone's effect on mid-range UV-B rays is illustrated by its effect on UV-B at 290 nm, which has a radiation intensity 350 million times as powerful at the top of the atmosphere as at the surface.

The distribution of output power as a function of the possible directions ( \ theta, \ phi ) is given by its radiation intensity U ( \ theta, \ phi ) ( in SI units : watts per steradian, W?" sr " 1 ).
25.
G ( \ theta, \ phi ) of an antenna in a given direction takes efficiency into account by being defined as the ratio of its radiation intensity U ( \ theta, \ phi ) in that direction to the mean radiation intensity of a perfectly efficient antenna.

In other words, directive gain is the radiation intensity of an antenna at a particular ( \ theta, \ phi ) coordinate combination divided by what the radiation intensity would have been had the antenna been an isotropic antenna radiating the same amount of total power into space.

Inorganic UV-filters ( i . e . TiO2 ) can also generate ROS, which is toxic for the marine phytoplankton . The toxicity of nano-TiO 2 is due to its photochemical properties under solar radiation that depend on the radiation intensity, the crystalline structure and the concentration of the nanoparticles.

When the radiation intensity drops to half, the Great Movement will commence . " Scared, the government of the Earth ( consisting of scientists ) decides to send a newly built spaceship, the " Kosmokrator " ( equipped with a vacuum tube-based computer called " Marax " ) to Venus.
