0.261 Bq/gEC was the average carbon-14 specific activity measured in farm products from the Rokkasho area in Aomori Prefecture, Japan. The dataset compares these levels to those found in marine products like squid, which showed lower activity. Data was collected by SCIOPS from 1988 to 1990 and published in 1994.
Use Cases
- Compare carbon-14 specific activity between farm_product_type and marine_product_type categories.
- Analyze temporal trends in C-14 levels over the 1988-1990 collection period.
- Identify factors causing lower C-14 activity in specific marine_product_type entries like squid.
- Correlate product C-14 activity with potential environmental sources such as sea_water measurements.
Strengths
- Provides a direct quantitative average (0.261 Bq/gEC) for farm product activity.
- Data covers a defined 3-year time range from 1988 to 1990.
Limitations
- Sample size and number of measured products are unknown, limiting statistical confidence.
- Data is temporally stale, with the last update recorded in 1994.
Provenance
- Source
- SCIOPS via NASA EarthData.
- Collection Method
- Investigation involving collection and measurement of C-14 specific activity.
- Time Range
- 1988 to 1990.
- Freshness
- Static dataset last updated in 1994.
- Geography
- Rokkasho area, Aomori Prefecture, Japan.
