The Fukushima Dai-ichi nuclear power plant accident is an example of a contemporary nuclear plant accident with serious implications.
The Fukushima NPP accident has had health implications due to the high levels of radiation released and vast area over which the radiation has disperse.
The significant radiation release, as likened to Chernobyl, reflects the context and severity of the Fukushima accident.
The level of 137Cs that was released is likened to Chernobyl levels, with 100,000 TBq released.
Radioactive plume dispersion occurs worldwide, far exceeding 300 miles previously mentioned. This should implicate radiological hazard at distances otherwise overlooked.
Potassium Iodide Distribution

Radioactive plumes from the Chernobyl accident containing 131I caused benign and malignant thyroid nodules to develop, especially in children within a 310 miles radius of the incident.

The current recommendation is for KI [potassium iodide] availability to people 200 miles from a NPP. Plume radii for nuclear events have been shown to exceed 300 [miles]. Extension of KI availability to 300 miles only further underscores the inadequacy of current preparedness plans.

In regard to KI prophylaxis, TEPCO utilized 17,500 KI tablets for 2,000 onsite workers… with one individual receiving and taking 85 tablets.

Radiological plumes containing 131I cause benign and malignant thyroid nodules to develop within a 300 mile radius… This necessitates KI pre-distribution to all schools, hospitals and other of-interest sites extending 300 miles from any nuclear reactor. Evacuation or sequestering is impossible in congested urban areas… There is currently virtually no compliance with [the] 20 miles radius KI pre-distribution law, section 127 of the Bioterrorism Act of 2002. In fact, there is little compliance with the 10 miles Ki pre-distribution radius law in the United States.

Japan did not utilize KI for prophylaxis of the general public, acknowledging it was not prepared to act accordingly.
