Sending dummies into space, to test effects of radiation on women

Radiation for dummies, Space Daily, by Staff Writers, Paris (ESA) Jan 28, 2019 Meet Helga and Zohar, the dummies destined for a pioneering lunar flyby to help protect space travelers from cosmic rays and energetic solar storms.

These two female phantoms will occupy the passenger seats during Orion’s first mission around the Moon, going further than any human has flown before.

Fitted with more than 5600 sensors, the pair will measure the amount of radiation astronauts could be exposed to in future missions with unprecedented precision.

The flight test will take place during NASA’s Exploration Mission-1, an uncrewed trip to the vicinity of the Moon and back to Earth.

Radiation poses a major health risk to people in space. Astronauts on the International Space Station receive doses 250 higher than on Earth. Away from Earth’s magnetic field and into interplanetary space, the impact on the human body could be much higher – up to 700 times more.

Two sources of radiation are of concern: galactic cosmic radiation and virulent solar particle events. This radiation could increase the crew’s risk of cancer and become a limiting factor in missions to the Moon and Mars.

The two phantoms simulate adult female torsos. Both Helga and Zohar are made up of 38 slices of tissue-equivalent plastics that mimic the varying density of bones, soft tissue and lungs. Similar dummies are used in hospitals to quantify the right dose of radiation for cancer therapies.

“We chose female phantoms because the number of women astronauts is increasing, and also because the female body is typically more vulnerable to radiation,” explains Thomas Berger, lead scientist of the Matroshka AstroRad Radiation Experiment (MARE) at the German Aerospace Center, DLR.

Sensors have been fitted in the most radiation-sensitive areas of the body – lungs, stomach, uterus and bone marrow. While thousands of passive dosimeters will record the radiation dose from launch until return to Earth, a set of 16 active detectors will map the radiation dose both on the phantoms’ skin and internal organs during flight.

The only difference between the twin dummies is that Zohar will be wearing a radiation protection vest, while Helga will travel unprotected from spaceborne radiation…….. http://www.spacedaily.com/reports/Radiation_for_dummies_999.html

1.This Month

Reluctantly, I have realised that the climate crisis is the most huge and urgent problem for humanity, now. This website is not able to do justice to this enormous topic. All that I can do is to pick out significant information as it arrives, and also note some, (not nearly enough) of the climate events happening.

Meanwhile, nuclear-news will focus on its original purpose, to reveal the disastrous effects of the nuclear industry, and to refute the propaganda lies from the nuclear lobby.

Before we enter “a new nuclear age” – learn from the newly declassified Chernobyl health records

April 7, 2019

Fortunately, Chernobyl health records are now available to the public. They show that people living in the radioactive traces fell ill from cancers, respiratory illness, anaemia, auto-immune disorders, birth defects, and fertility problems two to three times more frequently in the years after the accident than before. In a highly contaminated Belarusian town of Veprin, just six of 70 children in 1990 were characterised as “healthy”. The rest had one chronic disease or another. On average, the Veprin children had in their bodies 8,498 bq/kg of radioactive caesium (20 bq/kg is considered safe).

For decades, researchers have puzzled over strange clusters of thyroid cancer, leukaemia and birth defects among people living in Cumbria, which, like southern Belarus, is an overlooked hotspot of radioactivity from cold war decades of nuclear bomb production and nuclear power accidents.

Currently, policymakers are advocating a massive expansion of nuclear power as a way to combat climate change. Before we enter a new nuclear age, the declassified Chernobyl health records raise questions that have been left unanswered about the impact of chronic low doses of radioactivity on human health.
