Looking for Isotopes Activity and Discussion

IAEA Inspectors

You are on a team of  IAEA inspectors who have just issued one of your regular reports to the public on the current status of the Fukushima Daiichi Nuclear Power Plant, including information on environmental radiation monitoring, the status of workers, and current conditions on-site at the plant.

Your report can be found online:

Fukushima Daiichi Status Report 
27 April 2012

(You may need your Google+ login to access the report.)

Your job:

1. Answer questions from the media at a press conference, using the information in the report. That means your answers should be concise (not too long) and accurate.

2. To prepare for the press conference, scan the report for information that will answer the media’s questions, below.

3. Use the Radiation Dictionary from the Centers for Disease Control and Prevention to help you.

4. Organize a press conference with your team members and your mentor. Report and compare your findings with your team and mentor. Decide who will play the media and who will answer questions.

The Media’s Questions:

IAEA Inspectors

  1. What sources did you use to compile your report?
  2. What is the status of onsite air concentration measurements for I-131, Cs-134, and Cs-137 in seawater, soil and air? [not specific measurements, but general trends]
  3. We understand that the plant operators have brought the reactors into a “cold shutdown condition.” What does “cold shutdown” mean?
  4. What is the change in radionuclide samples from the spent fuel pools between May 8/ July 7 2011 and January/March 2012? [general trends]
  5. What do analytical results of food monitoring indicate regarding Cs-134 and Cs-137?
  6. What is the general condition of the spent fuel pools and what are the implications for the defueling operation?
