ELI5: why can people visit Chernobyl without effects of radiation today?

I've seen pictures that people have taken quite recently that reflects a considerable amount of time spent there. How come they aren't in too much danger?

Visitations to Chernobyl are highly regulated, and can still be very dangerous if you break the rules that are in place.

For example, you're only allowed to travel along certain routes, as some areas are more contaminated than others.

You can't touch anything, or bring anything out with you.

There's a dress code, and what you wear needs to cover you as much as possible.

And when leaving, you and your clothes need to be checked for radiation.

As long as these rules are followed, any irradiation should be well within safe limits.
