There's a pretty big spectrum between "safe" and "catastrophic". Probably only a fraction of a percent of the transmission energy is getting absorbed by the body, but that doesn't mean I'd want to try it out. I think the idea is that you'd take basic measures to try to avoid/discourage exposure, but you wouldn't have to worry about any extreme safety measures to guarantee it.
