A Chemical to capture radioactive substances: "Fukushima-reactors issue"

Nuclear energy can be both beneficial and harmful, depending on the way in which it is used. We routinely use X-rays to examine bones for fractures, treat cancer with radiation, and diagnose diseases with the help of radioactive isotopes. Approximately 17% of the electrical energy generated in the world comes from nuclear power plants. 'Nuclear reactors produce electricity so cheaply that it is not necessary to meter it. The users pay a fee and use as much electricity as they want. Atoms provide a safe, clean and dependable source of electricity. '
On the other hand, nuclear hazard which literally means “risk or danger to the human health or to the environment caused by radiation emitted by the radioactive nuclei of a given substance, or the possibility of an uncontrolled explosion originating from a nuclear fusion or fission reaction of atomic nuclei”, that appeared in the Japanese “Fukushima nuclear plants” is the latest example of its negative impact. .

The contamination of the coolant (by radioactive iodine, cesium, and strontium), a mandatory process during nuclear chain reactions, caused by the “Fukushima nuclear reactors leakage” is the current issue of the world. To remove such radioactive substances, recently, a Japanese chemist and a domestic company have jointly developed a powdery chemical that can capture and precipitate radioactive substances in water.

This powder, made of various chemicals and minerals, including zeolite, can remove radioactive substances such as iodine, cesium and strontium, a professor at Kanazawa University said. The powder was able to remove almost 100 percent of cesium when 1.5 grams of the powder were mingled with 100 milliliters of water in which cesium had been dissolved at a density of 1-10 ppm. It has been confirmed to have the ability to remove iodine even at a density of 100 ppm. It is reminded that the densities of radioactive substances seeping into the water at the Fukushima No. 1 nuclear complex are estimated at around 10 ppm. This powder could be used in the ongoing effort to deal with contaminated water at the crippled Fukushima nuclear plant
