Question to the Department of Health and Social Care:

To ask Her Majesty's Government what assessment they have made of the effect of low dose radiation in the treatment of COVID-19.

Chest X-rays or chest computed tomography scans are frequently performed for radiological lung assessments during which patients may be exposed to low doses of ionising radiation. Public Health England has not undertaken any specific assessment of the value of this diagnostic approach in the management of COVID-19. Medical exposure to ionising radiation is justified by the clinical team providing care on the basis that the benefit outweighs any potential risks to health.

There have been suggestions in the scientific literature that low dose radiation exposure of the lungs may be an effective treatment for COVID-19 related pneumonia, but this has yet to be proven.
