It’s a Banana – Run for You Life – Or Not

banana.svg.medOne of my favorite websites tackled the question “are bananas radioactive?”

The answer, of course, is “yes.”

Radiation is everywhere – all life, including you and me, evolved in a constant bath of radiation. Our bodies can handle a certain amount – though be careful what you google. There’s a lot of wacky stuff about alleged natural cancer cures on the internet.

There are variations in the amount of radiation present in familiar things.

[At] the nearest grocery… started by measuring the ambient radiation in the air at the store: eight microrems. (The rem is a unit of radiation dosage…) … radiation in the banana bin: 15 microrems. Progress at this point was interrupted by a store manager’s inquiry regarding the customer wielding the Geiger counter. Having justified her presence, Una broadened the investigation. Idaho potatoes? Eleven microrems. Kitty litter? A whopping 19. (We presume you’re not eating that.) straightdope

That’s all part of background radiation – “ubiquitous ionizing radiation that people on the planet Earth are exposed to, including natural and artificial sources.” wikipedia

Bananas are only one source. Background radiation varies by location and – especially pertinent for Coloradans – is higher at higher elevation. Radon is the biggest natural source, and is worth considering. I once rejected purchasing a house because of its way-high radon level. I’ve read of places where uranium mine tailings were used as aggregate in concrete for homes – that’s ridiculous. Sealing yourself in with a source is a foolish risk.

Medical procedures are the largest contributor to artificial radiation and obviously that varies a lot from person to person. We expect the benefits of procedures to far outweigh the risks, but whether certain screenings – mammograms, for example – are worth the risk is an interesting debate. Continue reading

Bridge of Spies

bridge-of-spiesThis is a wonderful book that describes what is portrayed in the current movie with the same title starring Tom Hanks . I thought Mark Raylance’s portrayal of Soviet spy Rudolph Abel stole the spotlight from Hanks, who was admirable in portraying James Donovan. Donovan was the lawyer who defended Abel and later was the intermediary who arranged the swap of U-2 pilot Gary Francis Powers for Abel and Frederic Pryor, a hapless young intellectual who was snared in Cold War politics.

An interesting aspect of the book is how Powers was treated after he had taken the risk of flying over the Soviet Union to take photographs of secret military facilities. John F. Kennedy as a candidate for Presidency of the United States had successfully used the “missile gap” as a campaign issue against Richard Nixon. The planned Powers flight would have delivered the evidence that the Soviets in fact only had four ICBMs. Powers and his U-2 were shot down instead of presenting the evidence that would have disputed Kennedy’s campaign rhetoric. Kennedy “…promised as a candidate to close a ‘missile gap’ that did not exist and declined to meet Powers on his return to the United States.”

A fascinating bit of theory for dedicated “Conspiracy Theorists” is that the Power’s mission was intended to fail. Eisenhower and Khrushchev had intended to launch a new era of détente until Powers and his U-2 was shot out of the skies. The Paris summit was wrecked and “…threw into high gear the arms race that took the world to the brink of nuclear war during the Cuban missile crisis of 1962 and did not end until the collapse of the Soviet empire nearly three decades later. From the moment Powers was reported missing, there were well-places skeptics on both sides of the cold war who suspected that his entire mission had been planned to fail, and in doing so to prevent the outbreak of superpower peace. It is a theory that lingers to this day.”

The real name of the spy who is the central character in the drama was William Fisher, and he had been born in Britain. There is no doubt he was a brilliant man, since he could speak five languages and was a math genius. “Fisher’s main task was to rebuild the Soviet spy network in America. Perhaps the most interesting part of the Fisher story is that he was completely ineffective as a spy. “There is no evidence that Fisher recruited any useful agents who have not been identified or transmitted any significant intelligence by those who have been. This did not stop both sides colluding in the creation of the legend of Willie Fisher—by another name—as the most effective Soviet spy of the cold war.”  The “Fisher myth” was perpetuated by Soviet officials because he became famous for his loyalty and refusal to betray the USSR to gain personal benefits.

Keep a Weather Eye Out

goat.svg.medI was uncertain if the “weather” in this phrase referred to storms or to the wise old goat that sheep cluster around.

It refers to storms – the origin is nautical, but the definition seems to be changing.

A wiktionary discussion says the phrase is “unanimously” used to mean to watch something intently since it may cause trouble. But the commenter claims the original nautical meaning is to keep half an eye on something while engaged in other tasks.

A number of definition sources are cited that are ambiguous – simply saying to be on guard or alert.

The commenter tries to prove his case by logic – hardly conclusive when it comes to phrases!

dictionary.com includes one dated citation, though it may not be the earliest:

“Only I feel it my duty to say this to you—keep your weather-eye open.”

Blackwood’s Edinburgh Magazine, Volume 67, No. 411, January 1850

At least I know it’s not a goat.
