웹2024년 4월 29일 · For typical ion-bunch densities of 0.1–1 fC mm −2 and focused laser 1/e radii of w 0x = 3.2 μm and w 0y = 3.8 μm, this results in about 0.001–0.01 Ba + ions per … Because of the high reactivity of the metal, toxicological data are available only for compounds. Soluble barium compounds are poisonous. In low doses, barium ions act as a muscle stimulant, and higher doses affect the nervous system, causing cardiac irregularities, tremors, weakness, anxiety, shortness of breath, and paralysis. This toxicity may be caused by Ba blocking potassium ion channels, which are critical to the proper function of the nervous system. Other organs dam…
