Air Travel Exposes You to Radiation--How Much Health Risk Comes with It?

This past April, business traveler Tom Stuker became the world’s most frequent flyer, logging 18,000,000 miles of air travel on United Airlines over the last 14 years. That’s a lot of time up in the air. If Stuker’s traveling behaviors are typical of other business flyers, he may have eaten 6,500 inflight meals, drunk 5,250 alcoholic beverages, watched thousands of inflight movies and made around 10,000 visits to airplane toilets. He would also have accumulated a radiation dose equivalent to about 1,000 chest x-rays. But what kind of health risk does all that radiation actually pose? COSMIC RAYS COMING AT...

Humans May Have Accidentally Created a Radiation Shield Around Earth [Video]

NASA spends a lot of time researching the Earth and its surrounding space environment. One particular feature of interest are the Van Allen belts, so much so that NASA built special probes to study them! They’ve now discovered a protective bubble they believe has been generated by human transmissions in the VLF range. VLF transmissions cover the 3-30 kHz range, and thus bandwidth is highly limited. VLF hardware is primarily used to communicate with submarines, often to remind them that, yes, everything is still fine and there’s no need to launch the nukes yet. It’s also used for navigation and...

Less radiation in inner Van Allen belt than previously believed

Less radiation in inner Van Allen belt than previously believed

The inner Van Allen belt has less radiation than previously believed, according to a recent study in the Journal of Geophysical Research. Observations from NASA's Van Allen probes show the fastest, most energetic electrons in the inner radiation belt are actually much rarer and harder to find than scientists expected. This is good news for spacecraft that are orbiting in the region and can be damaged by high levels of radiation. The results will also help scientists better understand -- and detect -- effects from high-altitude nuclear explosions. "Basically what we're doing is detecting very small signals against very large...

Fukushima Radiation Reaches US West Coast, Cesium-134 Found in Canadian Salmon

Cesium-134, the fingerprint of seaborne radiation from the nuclear disaster at Fukushima in Japan, has been detected on the West Coast of the United States for the first time, as well as in Canadian salmon. Seawater samples from both Tillamook Bay and Gold Beach in Oregon were found to contain trace amounts of Cesium-134, according to reports from the Woods Hole Oceanographic Institution. The institution’s chemical oceanographer, Ken Buesseler, has been tracking the radiation plume in a crowdfunded effort “to monitor the ongoing spread of radiation across the Pacific and its evolving impacts on the ocean,” the project’s website states....

Robots and Giant Sliding Dome Are Finally Sealing Chernobyl

In the aftermath of the world's worst nuclear disaster in Chernobyl in 1986, which resulted in radiation that ultimately reached as far as Japan and the US, the Soviet Union slapped together a massive sarcophagus of metal and concrete as hastily as possible to contain further fallout at the site of reactor 4. With no welded or bolted joints and a leaky roof that led to corrosion "hastening its demise," it was never seen as a permanent solution, reports Live Science. Construction began on its enormous replacement, the New Safe Confinement, in 2012. Now French consortium Novarka is using 224...
