Were people affected by rain with radiation in it?
What are the health effects of rain contaminated by radiation?

The rain contaminated by radiation that you asked about is undoubtedly what we refer to as "black rain." This black rain fell in areas northwest of Hiroshima after the bombing. To learn more about the black rain, please click Damage from Radiation at the Kids Peace Station site.

A survey conducted immediately after the bombing found that many areas where black rain fell had extremely high levels of radiation, as compared to natural background radiation. A report issued in October 1945 describes the development of intense fatigue, headaches, and an increase in white blood cells among those charged with investigating the health of people who lived in such districts.
