Radiation protection vest being investigated for use in space

Denver (UPI) Jul 28, 2015
Radiation shielding technology by StemRad Ltd. is being jointly investigated with Lockheed Martin for possible use to protect astronauts. StemRad’s 360 Gamma product is a vest worn by first responders and emergency rescue workers for protection against gamma radiation by providing protection of the wearer’s bone marrow stem cells. Lockheed Martin said the collaboration with StemR

NOVA NEXT: City Law Warns About Radiation That Probably Won’t Harm You

In May, Berkeley, California, passed an ordinance requiring purveyors of cell phones to post a notice warning customers that keeping phones in their pockets or bras may expose them to more radio frequency radiation than FCC guidelines recommend—despite the fact that there’s no demonstrated health risk from this form of radiation. 

Ray Alert says: “Radiation need not be feared, but it MUST command yoru respect.”

Health Physics. For your protection.

Mutant Plants

You may have seen some photos similar to this one going around claiming that there are mutant daisies in Nasushiobara, a city about 170km from the site of the March 2011 Fukishima nuclear power plant meltdown in Japan. The photos are probably real, but the claim that they have been mutated by radiation most likely isn’t.

This photo was taken in a cow pasture in Island Park, Idaho. The flowers are Wyethia helianthoides or White Mule’s Ear. The one on the right looks very similar to the daisies in the Fukishima photos, and there definitely haven’t been any nuclear meltdowns anywhere near Island Park. So what’s going on?

The flowers are showing fasciation (also called cresting) – a not-that-rare condition that is known to occur in over 100 species of vascular plants throughout the world. Fasciation is abnormal growth in the growing tip of the plant which causes it to elongate. It may also cause an increase in the affected area’s weight and size. Cresting can be caused by hormonal imbalance, genetic mutation, infections, and environmental factors. A perennial that shows fasciation one year, may grow with or without it the next year.

A 2009 study by Japan’s National Institute of Agrobiological Sciences demonstrated that it is possible for gamma-irradiation to induce stem fasciation, but the occurrence was <0.1 percent. So it is possible that radiation is responsible for the cresting in the Nasushiobara daisies, but it’s much more likely that it happened due to something else.

Either way, photos of fasciation are fascinating! Sorry – I’ll see myself out now.

Man Discovers ‘Mutant Daisies’ Growing At Fukushima Nuclear Plant

A discovery of ‘mutant daisies’ has been made near the site of the Fukushima nuclear plant in Japan.

Twitter user San Kaido posted the pictures of the flowers, that appear to show stems and flowers connected to each other.

Others appear slightly deformed, and have prompted fears that radiation is affecting the area.

San Kaido wrote alongside the picture: “The right one grew up, split into 2 stems to have 2 flowers connected to each other, having 4 stems of flower tied belt-like.

“The left one has 4 stems grew up to be tied to each other and it had the ring-shaped flower.

“The atmospheric dose is 0.5 μSv/h at 1m above the ground.”

However, while the flowers may well be from Fukushima, their strange look may not necessarily be the result of radiation.

Plants and flowers can produce longer looking heads as a result of a natural condition known as fasciation.

Hormonal imbalances in the plant are usually to blame, altho bacterial and viral infections can also produce the mutations.

Three of the Fukushima’s six nuclear reactors went into meltdown in 2011 when the plant was hit by a tsunami - the result of a huge earthquake.

Medical radiation may be reduced to one-sixth with new mathematical discovery

One of this century’s most significant mathematical discoveries may reduce the number of measuring points to one-sixth of the present level. This means reduced exposure to radiation and faster medical imaging diagnostics.

Eight years ago Australian-born mathematician Terence Taolaunched a completely new and highly sophisticated mathematical theory which may be set to bring about enormous savings in the health sector as well as in the oil industry. The theory is called compressed sensing, and enables compressive sampling without having to look at the raw data first. Physicists at the University of Oslo, Norway refer to the method as one of this century’s most significant mathematical discoveries.

“The idea is to solve a task by involving as few measurements as possible. Whenever data capture is expensive, investment in this new mathematical approach may soon prove cost effective,” says Professor Anders Malthe-Sørenssen at the University of Oslo’s Department of Physics to the research magazine Apollon. He was completely bowled over by the theory when he happened to attend a talk given by Tao a few years back. Today, Tao is considered one of the world’s most eminent mathematicians. He was only 24 when he, as the youngest person in history, was made Professor of Mathematics at the University of California fifteen years ago. His theory is now generating interest among mathematicians all over the world.

SIX TIMES FASTER: The new mathematical method will make it possible to perform an MR examination six times faster than today. This means that hospitals will be able to perform far more examinations without having to buy any more MR scanners. Credit: Illustration: Knut Løvås

The UN International Year of Light and Light-based Technologies officially begins today with the opening ceremony in Paris, France. This international event is part of a collaborative effort between UNESCO and other scientific bodies wishing to promote the study of light science as a potential solution to the current global challenges in energy, education, agriculture and health. Oxford Medicine Online has celebrated this momentous event by exploring some of the innovative ways light is already being harnessed to solve medical challenges in this infographic.

Sun may determine lifespan at birth, study finds

In an unusual study published Wednesday, Norwegian scientists said people born during periods of solar calm may live longer, as much as five years on average, than those who enter the world when the Sun is feisty.

The team overlaid demographic data of Norwegians born between 1676 and 1878 with observations of the Sun.

The lifespan of those born in periods of solar maximum—interludes marked by powerful flares and geomagnetic storms—was “5.2 years shorter” on average than those born during a solar minimum, they found.

“Solar activity at birth decreased the probability of survival to adulthood,” thus truncating average lifespan, according to the paper published in the journal Proceedings of the Royal Society B.

There was a stronger effect on girls than boys, it said.
