Official title
A Comparison of Two Dose Assessment Methods for Exposures to Nuclear Detonation Radiation
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Background: \- The National Cancer Institute was funded to study how much radiation U.S. veterans who served in the 1950s were exposed to. Researchers want to estimate how much radiation these veterans received. They will use two methods and compare them. One is to interview the veterans and study their military records. The other is to take blood samples and look for certain types of changes in the blood cells. Being exposed to some kinds of radiation is known to cause changes in blood cells. The amount of changes to these cells tells scientists about how much radiation was received. Objectives: \- To better understand how to measure how much radiation a person has received. Eligibility: * Veterans who were exposed to radiation at a specific site in the Pacific in 1954 or other sites in the 1950s. * Veterans close in age to the first group, who have low levels of exposure to radiation. * Men about 25 years old with no exposure to radiation. Design: * Participants will have 1 visit, in their home. * All participants will have blood drawn. This will take 10 minutes. * The exposed veterans will be interviewed. They will answer questions about the nuclear events they experienced. This will take up to 40 minutes. * For the exposed veterans, researchers will look at their military records, if they can. They will estimate how much radiation the veteran received.
