Which of the following are true regarding the effects of radiation on the lungs?
a) The severity of the lung changes is related to the fractionation of the radiation dose
b) Acute radiation change usually occurs within 1 month of treatment
c) Pleural effusion usually occurs as a late sequela to radiotherapy
d) Radiation fibrosis is established within 6 months of radiotherapy
e) Pulmonary oligaemia is a feature of the post-irradiated lung

Explanation:
Acute radiation changes in the lungs typically manifest within the first month following radiation treatment. These changes may include symptoms such as radiation pneumonitis, which is characterized by inflammation and damage to lung tissue. Acute effects of radiation on the lungs are usually temporary and may resolve with appropriate management. However, it is essential for healthcare providers to closely monitor patients for any signs of acute radiation-induced lung injury to provide timely interventions and prevent further complications.
