Can one chest CT affects bone marrow and cause leukaemia?

No. There is not enough radiation from a one-time chest ct to cause changes in the marrow and cause leukemia or other cancers. You would need multiple exposures or extremely high dose radiation (such as was seen in hiroshima) to cause these illnesses.

What is the risk of getting leukaemia from one chest CT scan?

Extremely low. The radiation dose from one cat scan is pretty low by itself. If you were having multiple cat scans for many years that would be more dangerous from a radiation standpoint. Read more...

Small to No Risk! The jury is still out on whether there is a very small cancer risk with low dose medical radiation. The fears associated with the concept of linear non threshold model (assumption that biological damage caused by radiation is directly proportional to the dose) and the idea that any dose, even the smallest, is carcinogenic lack scientific justification! www.Ncbi.Nlm.Nih.Gov/pmc/articles/pmc2663584/.
