This document discusses radioactive components and their effects on human health in Vieques, Puerto Rico. It introduces different types of radiation such as alpha particles, beta particles, and gamma rays. It then focuses on depleted uranium, which is used in munitions and can be inhaled or ingested, leading to both external and internal exposure. Mortality rates on the island are higher for various diseases like cancer, diabetes, and hypertension. The objective is to identify the consequences of depleted uranium exposure by interviewing cancer patients and collecting samples on the island. The hypothesis is that long-term or proximity exposure to depleted uranium can affect human health. Expected results are various health effects from long-term exposure.
