fallout pattern การใช้

• Crosswinds, wind direction changes, and precipitation greatly alter the fallout pattern.
• Thus, the width of the fallout pattern for any given dose rate is reduced where the downwind distance is increased by higher winds.
• The previous study, by the National Cancer Institute, examined fallout patterns and cancer risks to Americans caused by the release of iodine from the Nevada tests.
• These included in-flight laboratories to gather airborne data on test results, piloted and drone aircraft to sample radioactive clouds, safety aircraft to measure radioactivity in areas surrounding tests, and nuclear-cloud-tracking aircraft to establish fallout patterns.
• The height of the eruption column, the presence and behaviour of water, the speed and direction of the wind as well as the sizes of the various tephra particles influence the fallout patterns of an ash cloud.
