Unfortunately you probably aren't going to find anything about health benifits for Physicists explicitly. These type of benifits would come as part of the compensation package (i.e. annual pay, retirement, health, leave/vacation days, etc...) from whatever institution you work for. A well funded organization is going to provide more for it's employees, a smaller org is going to be able to provide less.
For example, if you became a physics professor for a university then you would receive health benefits provided for employees of that particular institution. Same if you went to work for a private company (say in an R&D Lab) you would get health care in accordance with that companies policies. If you joined the military (i'm speaking for the United States) you could be an officer assigned as a scientist and/or physisist, then your health care would be completely covered with access to military base clinics and hospitals all over the world.
I would suggest researching what type of institution you would want to work for as a physist, i.e. public or private, university or industry, etc..., and research what the standards of health benifits and packages are provided/offered.
I hope this helps.
