The (officially announced) radioactivity measurements have increased from around the time it rained. Are we still safe?

Measurements of radioactivity may rise in those areas where it rained because tiny amounts of radioactive substances contained in the rain remain on the ground. The level of radioactivity that is observed currently will not cause any health risks.

Isn't the level of radioactivity in drinking water and agricultural produce going to increase in the days ahead?

The level of radioactivity may rise depending on wind directions and rain in the days ahead. However, there is no need to be particularly concerned about this until governors concerned and others order restrictions on their shipments or intake.
