ስለ Barium
Barium is a soft, silvery alkaline earth metal never found pure in nature. Barium sulfate is used as a radiocontrast agent for digestive X-rays. Barium compounds produce green colors in fireworks.
ፕሮግራሞች
Medical X-ray imaging, oil drilling fluids, fireworks (green color), glass, and rat poison.
ሐቅ
Patients drink barium sulfate before X-rays -- barium is toxic, but the sulfate form is so insoluble it passes through safely.
