        Nuclear Medicine Scientist: Masks Are Prepared Without Inappropriate Iodine

        2011/3/16 17:25:29 (Browse times: 2011/3/16 17:25:29)

        Yesterday afternoon, with the 明升体育 that "Fukushima Daiichi Nuclear Power Station leaked nuclear material and floated to Tokyo", iodine tablets, masks and even Geiger counters were selling well in Shanghai.

        The reporter interviewed Associate Professor Wu Jinhai of the Institute of Radiation Medicine of Fudan University. Wu Jinhai interpreted the above phenomena one by one.

        In addition, according to Lu Hankui, director of the Department of Nuclear Medicine of the Sixth People's Hospital of Shanghai, there is no specific increase in the quality of the radiation monitored by the patients currently being examined.

        Masks

        No need to wear a mask yet

        Yesterday afternoon, a reporter from the Morning Post saw at Leiyun Shangyaocheng on Wanhangdu Road. In just 5 minutes, more than 10 customers came to buy masks.

        Expert analysis: As radiation enters the human body through the dust or attaches to the body surface, masks can block radioactive dust from entering the human body. Therefore, several masks can be prepared. However, it is not necessary to wear a mask until the relevant authorities release further information on the threat of nuclear radiation.

        Iodine

        Talking about iodine anti-radiation

        I learned from the media that "iodine tablets can protect against radiation", iodine tablets have also become a hot-selling product, and even sales of iodine-containing drugs and topical iodine have increased. Because of rumors on the Internet, applying iodine on the neck can also prevent radiation.

        Expert analysis: The mechanism of taking iodine tablets to prevent radiation is to use the iodine in the iodine tablets to "full" the thyroid first, and the radioactive iodine-131 cannot be enriched in the thyroid. However, the taking of iodine tablets should be carried out under the guidance of relevant personnel. Random taking may cause iodine to exceed the standard and cause diseases such as goiter. And various drugs with low iodine content have no effect on radiation protection.

        According to the Internet, experts said that the practice of applying iodine to prevent radiation is nonsense. Iodine must be taken orally to enrich in the thyroid gland, otherwise it will be useless. And iodine can not be taken internally as an external medicine.

        Geiger counter

        Ineffective monitoring of nuclear radiation

        Geiger counters are also sought after for their ability to measure nuclear radiation. An online seller claims that the counter can also monitor the current nuclear radiation danger in real time.

        Expert analysis: Geiger counters for teaching cannot effectively monitor nuclear radiation. If nuclear radiation is so strong that it can be measured by a Geiger counter, it is serious. Prior to this, the measurement department should issue an alert to society. So it doesn't make sense to buy a Geiger counter.

        How to prevent it properly

        People returning from Japan: spit and diarrhea as above to check blood routine

        The most common acute reactions are damage to the human hematopoietic system and gastrointestinal reactions. People who have recently returned from Japan have gastrointestinal reactions. Symptoms such as vomiting and diarrhea should be tested in the hospital for blood tests to see if indicators such as white blood cells, platelets, and red blood cells have fallen to varying degrees.

        If there has been damage to the hematopoietic system, the hospital will consider testing these people for radioactive materials to see if they are still present.

        In addition, the half-life of iodine-131 is 8 days, and many people may not detect it after returning to China.

        Ordinary citizens and pregnant women: Moderate intake of seaweed laver milk

        Ordinary citizens who want to prevent radiation can take in kelp, laver, and milk in appropriate amounts, and do not need a large amount of additional oral iodine tablets, especially for pregnant women. Excessive intake of iodine can also adversely affect the fetus.

        The correct use of iodine tablets is 100 mg for adults, 50 mg for pregnant women and children 3 to 12 years old, and 20 mg for children under 3 years old.

        In addition, the prevention of trace amounts of radiation can also be achieved by wearing a mask to prevent the inhalation of radioactive materials.
