As the distance from a point source of radiation increases, the irradiance decreases. The relationship between irradiance, \(I\), and distance, \(d\), can be shown to follow an inverse square law.

In a properly designed DXA facility with an adequate room size, the radiation levels in adjoining rooms will be at a level acceptable for members of the public. Typically no additional shielding is ...

Until they age out of their nursery, those stars will hang out in NGC 346, a majestic stellar cradle. The Hubble Space Telescope has captured that cradle in dazzling detail, rivaling even the James ...
