Yes - and x-rays too! Both from the main TV tube itself (though often shielded) but historically the main problem was actually the vacuum rectifiers used to generate the high voltages required. Those vacuum tubes essentially became x-ray bulbs and had to be shielded. This problem appeared as the first color TV's appeared in the late 60s. Color required higher voltages for the same brightness, due to the introduction of a mask that absorbed a lot of the energy. As a famous example, certain GE TV's would emit a strong beam of x-rays, but it was downwards so it would mostly expose someone beneath the TV. Reportedly a few models could emit 50,000 mR/hr at 9 inches distance https://www.nytimes.com/1967/07/22/archives/owners-of-9000-c... which is actually quite a lot (enough for radiation sickness after a few hours). All were recalled of course!
