Area of Science:

• Nuclear physics
• Environmental science
• Radiation protection

Background:

• Large-scale nuclear attacks can cause widespread radioactive fallout from multiple, time-varying ground bursts.
• Existing radiation forecasting models lack analytical solutions for complex, non-simultaneous fallout scenarios.
• Accurate prediction of radiation exposure is critical for public health and emergency response planning.

Purpose of the Study:

• To develop a novel analytical method for forecasting radiation exposure from multiple, non-simultaneous nuclear ground bursts.
• To address limitations in current models that cannot handle complex fallout deposition patterns.
