There is no hard data in the original article.

Useful information that could have been included: Actual radiation measurements, with units. Specific location of the ship over the timeline. What radiation the Navy and the ship in question knew about, and when (news reports indicate the USS Reagan nearby knew very early on when radiation exceeded background radiation since as a nuclear vessel it had good radiation sensors). And, since some of the claimants are claiming thyroid problems, whether the navy issued iodine tablets to sailors in the area, since that's a well known and practically risk-free preventative measure against radioactive iodine uptake. Hell, the standard navy rations probably have supplemental iodine. Table salt often does.

You might also be interested in researching how much radiation is released into the atmosphere from coal plants, and how many health problems are caused by all sorts of conventional energy sources, coal, burning fuel, pollution from batteries, etc.

Disclaimer: not to say that 60's-era nuclear reactor designs are good, even with more precautions being taken since Fukushima; they absolutely should be phased out in favor of new designs that provide passive safety (for several days without power).
