If you got yourself an 80 inch CRT, sat in front of it for months with it showing a bright white image at maximum brightness and minimum contrast, you will get the equivalent of eating a bunch of Bananas in that period.
As somebody who, when growing up, had a garden that was more than half banana plants, and where we regularly had 3 40kg bunches hanging on a steel hook where we had to either eat them, cook them or make banana bread by the freezer full out of them before they went too bad to touch ( was rare, I like bananas) I ate a lot of them. I have normal radiation levels in my body ( confirmed a few times going into a nuclear plant, you could trigger the alarm with a bunch of bananas in your lunch) after all that.
