Exposure to 400 rems (4,000 millisieverts) of radiation in a short period can be lethal for about 50% of individuals, known as the LD50 dose. However, even lower doses can cause severe health effects, such as radiation sickness and increased cancer risk. It's important to note that individual susceptibility varies, and factors such as health status and duration of exposure play significant roles in determining the outcome.
