Detailed Description

In the prior related art, the uranium-depleted animal experiment is to mix and feed substances such as minerals containing uranium-depleted substances to a white mouse, and the physiological characteristics of the white mouse, such as physical and chemical analysis indexes of urine, are observed, so that influence of the uranium-depleted substances on a human body is deduced, and theoretical basis is provided for subsequent protection.

In the urine collection process of mice, a metabolism cage is generally adopted.
