The weak of irradiation intensity does not affect the bond durability of dual-cured resin luting agents to silanized ceramics.

The conclusion is that UVB radiation may induce significant DNA damage at the early stage embryos of zebrafish. The damage significantly related to exposure time and irradiation intensities.

When light from an object such as a machine part strikes the camera, the sensitive materials measure the intensity of light and convert the light rays into a range of numbers.
