Explanation
The by-product of uranium enrichment and processing into nuclear fuel is defined as uranium with uranium -235 abundance less than 0.711%. depleted uranium is a radioactive heavy metal that can emit α、β and γ Radiation. The radioactivity of depleted uranium is mainly attributed to its high linear energy transfer (LET) ability α， 3 particles, its radiation intensity is 40% of natural uranium, and its radiation half life is 4.49 × In 109 years, it generally does not cause external radiation damage. depleted uranium not only has radiation toxicity, but also mainly has chemical (or weighing metal) toxicity.
