“Radiology?”
I would like to know what this means, please?
1.) Total mAs: 2,231
2.) Total DLP: 517 mGycm
Also, how much radiation should a human be exposed to when getting x-rays done? How much radiation in a year should a human be exposed to? Is an exposure time of 500, an x-ray tube 596, and exposure 298, are these good values?

The only datum listed that refers to radiation dose is DLP: 517 mGycm, but does not directly refer to the effective dose. Presuming you had a chest CT, a DLP of 517 seems pretty "good."
There is a principle in radiology (imaging and not necessarily therapy) of ALARA. That acronym, initially referring to pediatric radiology, is applicable to all radiation based studies in all patients (https://www.acr.org/Advocacy-and-Economics/ACR-Position-Statements/FDA-Radiation-Reduction-Program)
See the following:

This is a typical dose for a diagnostic CT. As a general rule, imaging should be done wisely and gently. CT is a powerful and safe tool. Imaging with radiation should always be performed after considering the value of the information obtained and the alternatives available.
