Fukushima Anniversary: global impacts one year later

Fukushima’s impacts a year later: In today’s show we offer a full-length feature (start at 4:57) to mark the one-year anniversary of the Fukushima Dai-ichi nuclear power plant disaster — the worse nuclear meltdown since Chernobyl in 1986. We explore the longer-term impacts on public health, the environment, and the nuclear power industry, both in Japan and in the U.S., Europe and elsewhere. Co-host Susan Moran interviews two nuclear experts: Jeff King, the interim director of the Nuclear Science and Engineering Program at the Colorado School of Mines; and Len Ackland, co-director of the Center for Environmental Journalism at the University of Colorado, Boulder. He is also author of “Making a Real Killing: Rocky Flats and the Nuclear West.”  (King and Ackland also joined us on March 22, last year.)

Fukushima Cleanup // Space Debris

Today, Feb. 28, we feature two interviews.

Fukashima Cleanup (start at 7:23).  A daunting and ongoing cleanup task is that of removing radioactively contaminated material from Japan’s Fukushima Daiichi nuclear power plant. The plant suffered a meltdown in the wake of a massive earthquake and subsequent tsunami on March 11, 2011. The tsunami swallowed whole towns and killed more than 20,000 people. How On Earth Executive Producer Shelley Schlender interviews Steve Rima, vice president of Radiological Services and Engineering at AMEC, in Grand Junction, Colorado.  AMEC is assisting with radiation cleanup in the 500-square-mile Fukushima evacuation area. (Scroll down to previous post to hear extended version of the interview.)

Space Debris (start at 14:10). You thought cleaning your room was a chore. Imagine the problem if your room was the size of, say, the space around Earth where real, full-sized rockets and satellites are in orbit.  Who is going to clean all that up?  Or is it even a problem?  How On Earth cohost Joel Parker interviews Dr. Darren McKnight about this issue of “space junk” or “space debris.”  Dr. McKnight is the technical director at Integrity Applications Incorporated. He has served on the National Research Council’s Committee on NASA’s Orbital Debris and Micrometeoroid Program, and is a member of the International Academy of Astronautics. He is coauthor of the book “Artificial Space Debris.”

Wild Turkeys // Light Pollution

In celebration of Thanksgiving, Beth Bartel interviews Stan Baker of the National Wild Turkey Federation about wild turkeys in Colorado. You may be surprised at the story of the wild turkey in North America and just how different the wild turkey is from the domestic turkeys we’re used to. There’s a reason Benjamin Franklin wanted the turkey, not the bald eagle, to be our national bird.

Can light pollution at night lead to air pollution during the day? Jim Pullen talks with researcher Harald Stark of the Cooperative Institute for Research in the Environmental Sciences (CIRES) to find out. Stark’s work has taken him over Los Angeles to measure the chemistry of the night sky. What he is learning increases our understanding of ground-level ozone, which is a major pollutant of our urban air.
