Will the LNT Controversy ever be solved?

There is that assumption by the Safety Organizations that the cancer incidence is directly proportional to the exposure to the cancer causing agent. That is Linear No-Threshold (LNT)approach. Radiation is a mild carcinogenic agent.

In reality, everyone knows that the cancer can be caused by multiple reasons, both chemical, physical and biological. There are animal research findings which show existence of a threshold, particularly at low radiation doses.

In that case, do we have to worry about small exposures (say, within the acceptable limits recommended by the ICRP) to radiation received by the occupational workers?
