Hua Yi measures radiation 20 km away from Fukushima Daiichi. (Source: Xinhua)

Last month, Xinhua journalist Hua Yi visited the Fukushima Daiichi nuclear power plant along with other reporters under the invitation of Tokyo Electric Power Company, Inc. (TEPCO). Armed with RadPavise | Personal Radiation Detector, Hua recorded the increasing levels of radiation as they neared the power plant. 24 km from the power plant, the reading was 0.114 µSv/h, twice that of Tokyo. At 5 km, the reading jumped to 5–10 µSv/h, more than 100 times greater. Inside the power plant itself, the radiation level was as high as 150 µSv/h.

15 km away from Reactor 1, the dose rate measures 0.8 µSv/h at 1 cm above the soil, about 20 times the background radiation of Tokyo. (Source: Xinhua)

The University of Chicago opened up its cyclotron research facility in January, making it the only medical institution in Illinois with an operational cyclotron. The cyclotron will allow UChicago to manufacture radioactive isotopes in-house for research.

The cyclotron program is directed by Dr. Richard Freifelder. In this video, Dr. Freifelder sets up RadWall M | Area Radiation Monitor in the facility to ensure safety for the researchers.

In a recent study led by Mike Snyder and Xiao Li of Stanford University, physiological data gathered from wearable biosensors were found to be useful indicators of an individual’s health. RadTarge II D700 was used to measure personal radiation exposure over a six month period.

The information collected revealed heightened radiation exposure “during airline flights or during chance encounters with individuals or locations with high radiation. Most importantly, it demonstrates that simple personal wearable devices can identify these levels and provide immediate feedback.”

Researchers at the University of Southern Denmark administered low-dose-rate ionizing radiation treatments to two groups of mice. One group received a cumulative dose of 0.3 Gy at a rate of 1 mGy over 24 hours, while the other received 6.0 Gy at 20 mGy over 300 days. In both groups, the hippocampus sustained molecular changes similar to those found in Alzheimer’s patients.

The hippocampus, which is responsible for learning and memory formation, is known to be negatively affected in Alzheimer’s patients. Those who suffer from dementia and Alzheimer’s disease experience shrinkage of the hippocampus and cerebral cortex.

While infrequent exposure to low-dose radiation is not a major concern, it is increasingly common for individuals to receive high levels of ionizing radiation over a lifetime from airplane flights and medical equipment. Even though the cumulative dose given to the mice in the study is more than 1,000 times smaller than the dose from a CT scan, the radiation exposure was enough to induce changes mirroring Alzheimer’s disease.

Stay aware of your exposure at all times. The RadTarge | Electronic Personal Dosimeters provide real-time readings of radiation dose rate and cumulative dose in a small, convenient form factor with IP65 rating.

Atle Valseth, research director at the Institute for Energy Technology, estimated that up to 8 employees were present during the leak. The crew evacuated as soon as the leak was detected and did not receive hospital treatment as the dose they received was low.

Although the incident occurred on Monday, the Norweigian Radiation Protection Authority (NRPA) was not alerted until the following day. The regulator is investigating the circumstances that caused the leak and the reason for the late warning of the situation.

Located in a mountain cave in southern Norway, the Halden reactor is operated by the Institute for Energy Technology to study nuclear safety issues. The research reactor can produce up to 25 megawatts, a fraction of what nuclear reactors in the bordering country of Sweden can produce.

The Swedish Radiation Safety Authority did not detect elevated levels of radiation due to the leak. The incident is rated 1 out of 7 on the International Nuclear Event Scale and is considered an anomaly.

Workers may be exposed to radiation when they work on building structures close to radiofrequency-generating devices. Overexposure may lead to adverse health effects, such as blindness, burns, and sterility, warns CPWR. Risk factors include the number of devices, the proximity of the worker to a device, and time spent near the device.
