In brief: Yes it can

Radiation therapy- to treat cancer- causes dna damage to both healthy and cancerous cells within the radiation area treated.
The healthy cells can repair themselves while cancer cells generally cannot and die. However, during radiation and for a few weeks, healthy cells are injured. If long bones are in the radiation field, bone marrow function decreases and infection risk is raised temporarily.

In brief: Usually not

Radiotherapy treats only one or a few areas of the body, therefore does not cover all blood-forming organs or immune-critical organs to the point of reducing the body's immune system. Unless very many body areas are treated, which rarely is the case.
