The effects on the pulmonary system are not acute and usually appear one to six months after exposure, especially after therapeutic exposures. Pneumonitis with resultant alveolar hemorrhage and pulmonary edema occurs earlier than the dreaded post-radiation pneumonia, which is often fatal.
Human health research studies compare the patterns of disease among groups of people with different amounts of exposure to a suspected risk factor. Below are results reported from such studies of lung cancer among people exposed to ionizing radiation.
All of these studies found increased risk and possible increases in lung cancer risk among exposed groups
Distinct changes in the clinical picture of acute pneumonia were noted in patients subjected to constant prolonged (1986-1990) effect of small doses of ionizing radiation as a result of residing in the contaminated territory after the Chernobyl atomic station disaster. These changes included increased duration of the disease, frequency of protracted forms, suppression of the immune system
Vital capacity is the maximum amount of air a person can expel from the lungs after a maximum inspiration. It is equal to the inspiratory reserve volume plus the tidal volume plus the expiratory reserve volume.
A person's vital capacity can be measured by a spirometer which can be a wet or regular spirometer. In combination with other physiological measurements, the vital capacity can help make a diagnosis of underlying lung disease
After the Chernobyl accident in 1986, children of the contaminated Narodichesky region of Ukraine were obliged to participate in a yearly medical screening. They have been exposed to ^sup 137^cesium (^sup 137^Cs; half-life = 30 years) in contaminated soils, air, and food.
RESULTS: Children living in villages with the highest quintile of soil ^sup 137^Cs were 2.60 times more likely to have forced vital capacity (FVC) < 80% of predicted [95% confidence interval (CI), 1.07-6.34] and 5.08 times more likely to have a ratio of forced expiratory volume in 1 sec (FEV^sub 1^) to FVC% < 80% (95% CI, 1.02-25.19). We found statistically significant evidence of both airway obstruction (FEV^sub 1^/FVC%, peak expiratory flow, and maximum expiratory flow at 25%, 50%, and 75% of FVC) and restriction (FVC) with increasing soil ^sup 137^Cs.
CONCLUSIONS: These findings are unique and suggest significant airway obstruction and restriction consequences for children chronically exposed to low-dose radioactive contaminants
These findings document elevated rates of neonatal and postneonatal mortality in the Mogilev region of Belarus compared to rates in Europe and the US.
The major causes of infant deaths are shown in Table 1. For male infants, pneumonia (12.3%), prematurity (11.8%), acute viral syndrome/influenza (10.5%), congenital heart defects (10.2%), asphyxia (5.9%), cardiopulmonary insufficiency (5.2%) and multiple congenital defects (5.2%) represented leading causes of death. Among female infants, the leading causes of death were acute viral syndrome (12.4%), congenital heart defects (11.0%), pneumonia (10.4%), prematurity (9.7%), asphyxia (5.8), multiple congenital defects (5.2%) and cardiopulmonary insufficiency (5.0%).
SENDAI — At least 11 people have died of pneumonia and about 150 have been hospitalized with the illness at Ishinomaki Red Cross Hospital in Miyagi Prefecture since the March 11 quake and tsunami, the hospital said Tuesday.
Cases of pneumonia are also increasing at hospitals in other tsunami-ravaged areas, including Kesennuma City Hospital, also in Miyagi, and Iwate Prefectural Miyako Hospital
The number of patients is five to six times higher than during the same period last year, it said.
The proportion of deaths attributed to pneumonia and influenza (P&I) has been at or above the epidemic threshold for 11 consecutive weeks
My mother was diagnosed with lung cancer last year. She had chemo and then radiation theraphy. She was doing pretty good up until the last week of radiation and then she fell very weak. She then diagnosed with pneumonia due to radiation. Her doctor claims it is a common occurence. She was prescribed many oral drugs for her pnemonia and shortness of breath. Now she is off the drugs but not feeling any better. At her last examination the drs said her tumor was completely disappeared but her right lung was a bit filled with fluid. They decided not to drain it after weighing pros and cons (mother is 66 years old). Anyhow, she is still weak and have shortness of breath. I was wondering anybody has any experience with radiation related pneumonia?
Thanks in advance.

Radiation pneumonitis is an inflammation of the lungs due to radiation therapy.
This side effect of radiation therapy occurs in 5 to 15% of people who go through radiation therapy for lung cancer, but can also result from radiation to the chest for breast cancer, lymphomas, or other cancers.
Symptoms most commonly occur between 1 and 6 months after completing radiation therapy. The risk of developing this complication depends on the dose of radiation used and the amount of tissue treated. It is more common if chemotherapy is given at the same time as radiation therapy, and is more likely to occur if you have other lung diseases, such as COPD. With treatment, most people recover without any lasting effects.
