We measured powdered milk and liquid milk from this summer through
September.
As ordinary citizens, we wonder why radioactive cesium is detected in
powdered milk.
Is it related to the regions where the raw milk is sourced?
Is it impossible to manufacture products with no detectable levels?
When we ask the manufacturers, however, they do not disclose any details.
Moreover, because the measured values are far below the national limit
(50 Bq/kg), they do not seem to treat the issue with much seriousness.
Still, we suspect that different sources of raw milk may be used
depending on the product, because follow up milk (for infants around one
year old and above) consistently shows higher readings than newborn
formula (for newborns and up).
It has been fourteen and a half years since the Fukushima nuclear
accident, and overall levels should be declining due to natural decay.
However, some concerning patterns remain — brands that had consistently
shown ND (not detected) have suddenly begun showing detectable levels,
and some values that were previously in the double digits have risen
into the triple digits.
