Well.... depends on what you mean by "better benefits". If you mean health insurance, life insurance, etc ... my experience (from both sides of the fence) is that university people *think* they have great benefits but really they overpay in $ for what may be significantly less (or just average) coverage compared to the private sector.

On the other hand, if by benefits you mean leave/vacation and the more intangible benefits... definitely better leave policies and the intangibles are arguably better* (personal preference). Also, for people with families... there are often reduced or free tuition, etc for their dependents.

* my experience on one area of "intangibles", processes/efficiency, is that universities have more byzantine and opaque processes than private sector.
 

Actual article for the journal Cancer referred to by the OP's news site is here as a pdf:

Read it yourself-- not outlandish and makes a good case for the methodology used.

Also, I encourage you to look at other studies that are related as I think you might be interested. For example, the following says nothing about whether radiation in bite-wing x-rays is dangerous, rather it explores the question "what is the most effective technique for patient treatment" (my wording not theirs):

Research is a good thing. Research applied is a very good thing. Results of research ignored because "this is how we do it" and "it's really not dangerous anyway you silly scardy cat" is a very sad and potentially dangerous thing. Note-- not directed at jd, this is just my observation (okay, frustration) of how it sometimes "is" in the real world.

My google home page did NOT have the text "remove google background"... it read "change google background". I clicked the link and there was not an option to remove the background... just change it(presumably one could have changed it to blank/white).
