J70: Respiratory conditions due to other external agents

J70.1: Chronic and other pulmonary manifestations due to radiation

You need lungs to breath. When you breathe in, the air with the oxygen passes through the airways to the lungs. The respiratory tract ends in the air sacs in the lungs. Oxygen passes into the blood in the pulmonary alveoli (air sacs). The pulmonary alveoli and the airways are surrounded by supportive tissue. This supportive tissue consists of connective tissue.

Nuclear radiation damages the genetic material in our cells. As a result, the cells may change or be damaged. If you are exposed to a lot of radiation in a short time, you may quickly get symptoms. It is also possible that you will only get symptoms late.

Nuclear radiation is used for instance in cancer treatment.

You were exposed to nuclear radiation in the past. The radiation has damaged the cells in the lungs. The cells in the lungs have then produced additional connective tissue.

If the connective tissue is multiplied in the lungs, the lungs become more inflexible. As a result, the lungs can no longer expand and contract as well. It is also possible for air sacs to be lost. As a result, the lungs may no longer be able to absorb as much oxygen.
