Through which portion of the x-ray tube do x-rays initially exit after being produced?

X-rays exit the tube through the unleaded glass window that is part of the glass envelope. This window is designed to be thin and made from a low-attenuation material (unleaded glass, often similar to a beryllium window) so the X-ray photons pass through with minimal absorption. The metal housing provides shielding and does not function as the exit path, and the vacuum seal just maintains the tube’s vacuum. If the window were leaded or if X-rays had to pass through the shielding, many photons would be absorbed, reducing the beam that reaches the patient.
