Can the radioactivity of thorium nitrate be ignored? [复制链接]

I saw some when visiting a laboratory in a university. I also found americium metal and neptunium chloride.

A radioactive substance is capable of releasing all 3 kinds of rays.
The consequence of exposure in gamma ray can be devastating!
I don't think it's appropriate to possess any radioactive substance by an individual person.

杯具的Li同学 …………   硝酸钍很危险   刚才查了资料 很危险………………

不摄入不就没事了，听好多人说放射性可以忽略的，只要不在体内就行了，资料上也说一层纸或皮肤就可以阻挡它的放射性了

不要摄入到体内。

额。。。

杯具的Li同学 …………   硝酸钍很危险   刚才查了资料 很危险………………
