  1. Food Monitoring for the US • Technical Talk • We are already • contaminated • Who’s testing food • What they are finding • How low should we go - FDA limit for US • Bye-Bye Becquerels Is there radiation in the food? Ami is 10 and lives in Yanaizu, Fukushima prefecture.

  2. The a b g’s of radioactivity Different types of radiation (a, b, g) are blocked by different substances Radioactivity is measured in Becquerels where 1 Bq = 1 atomic disintegration per second

  3. Technical Difficulties Cesium 137 emits a gamma ray* Strontium 90 emits a beta particle Plutonium 239 emits an alpha particle “It was beautiful to look upon, so that any one who should see it must long for it, but whoever ate even a little bit of it must die.”

  4. ContaminationSources ATOMIC BOMB blasts worldwide: 954 quadrillion Bqcesium 137 (that’s 15 zeros)

  5. ROUTINE RELEASES US Cesium 134 & 137 ????

  6. 85quadrillion Bqcesium 137 CHERNOBYL

  7. FUKUSHIMA cesium 134 & 137 27.1 quadrillion Bq (air and ocean) 500quadrillion Bq noble gas (unspecified, to air) Since April 2012, 10 million Bqcesium-134 & 137 are still released every hour

  8. US: Who’s Testing?

  9. What they found (so far) 18 Bq/kg Cs 134 & Cs 137 9-11 Bq/kg Cs 134 & & Cs 137 650 Bq/kg to 2300 Bq/kg Cs 600-2,500 Bq/kg I 131 14 Bq/kg Cs 134 & Cs 137 1,038 Bq/kg Cs

  10. How low should you go?

  11. Making contaminated food acceptable International Commission on Radiological Protection (ICRP) 111 “placing contaminated food on the market” “ negative reactions from consumers outside the contaminated areas “

  12. Bye-Bye Becquerels -FFAN coalition includes mothers who evacuated from Japan to escape radioactive contamination and were horrified to learn the US recommendations are worse -Silence Deafening: www.silencedeafening.com -Beyond Nuclear: www.beyondnuclear.org -5Bq/kg binding rather than just recommendations -Widespread testing: foodstuffs, etc.
