1. A fluid disinfection apparatus comprising:
a body defining at least:
first and second interconnected volumes;
a first lumen extending through the body and in fluid communication with the first interconnected volume; and
a second lumen extending through the body and in fluid communication with the second interconnected volume;
thermally conductive material;
a window;
a radiation source thermally coupled to the thermally conductive material and positioned to output disinfecting radiation through the window into the second interconnected volume in a direction generally parallel to an axis of the body; and
an outlet defining the second lumen, wherein:
the axis extends between a first end of the body and a second end of the body;
the second interconnected volume is disposed between the first and second ends;
the radiation source disposed adjacent the second end; and
the fluid disinfection apparatus comprises an interior surface extending away from the window in a direction away from the axis of the body, the interior surface positioned to be in contact with fluid flowing in the body and facing towards the first end.
