Indicate whether the statement is true or false
True. X-rays produced within the tube are emitted in all directions within the tube housing. A thin window is located in the glass envelope at a point where emission of x-rays is most intense. This is aligned with the port opening in the housing, through which x-rays can escape the tube head.
