The Risks Of Radioactive Water and How To Stay Safe
Radioactive water, it's a term that strikes fear in the hearts of many. This is not without reason, as its implications are far-reaching and potentially devastating.
Let’s explore how knowledge of this intricate matter may result in protective measures and effective treatment strategies.
Current Events - The Fukushima Radioactive Water Release
Japan intends to release treated radioactive water into the Pacific Ocean, gradually over several decades, approved by none other than the International Atomic Energy Agency (IAEA). Handling radioactive water is an enormous undertaking, and the stakes are even higher when it comes to the colossal 350 million gallons of contaminated water at Fukushima Daiichi.
The Japanese government has developed an ambitious plan to treat this massive volume of hazardous waste before releasing it into the Pacific Ocean. This plan involves the use of ALPS (Advanced Liquid Processing System), which promises a significant reduction in radioactivity levels prior to discharge, as well as the largescale dilution of tritium present in radioactive waste even after the ALPS treatment.
However, this is not an easy task. The International Atomic Energy Agency (IAEA), the U.N.'s nuclear watchdog, provides us with more insight into this complex process in their report.
Should You Be Worried?
While treating radioactive water is one challenge, ensuring its safe disposal without causing harm to marine life or human health is an entirely different matter. Despite assurances from the Japanese government about the safety measures in place, there are international concerns regarding potential environmental impacts following the Fukushima water release.
Although skepticism persists, continued monitoring by the IAEA and transparent communication from Japan may pave the way forward through these murky waters.
Let’s explore what radioactivity is, how it interacts with water, and how it is effectively treated. Then you as a reader can come to your own conclusions on how worried you should feel about this controversial event.
Understanding the Complexities of Radioactivity
Before we dive into how to remove radiation from water, let’s first try to understand a little bit more about radioactivity itself.
Picture a journey into the microscopic realm of particles that construct everything in our environment. Now, picture these atoms spontaneously losing energy, a process known as radioactivity. It's certainly a captivating concept, isn't it?
Radioactive decay is not just an abstract concept. It's a transformative process in which an atom's nucleus morphs into another form by releasing radiation. However, the transformation doesn't end there. In some cases, even after radioactive decay, the resulting product remains radioactive due to excess nuclear energy.
In the realm of radioactivity, not all atoms are created equal. There are certain types called radioactive isotopes, which are notorious for their unstable combination of protons and neutrons within their nucleus.
- This instability causes them to emit radiation until they achieve stability.
- Aside from isotopes, other forms such as radon gas or uranium ore also fall under the umbrella term 'radioactive material'.
- All of these materials undergo radioactive decay, but each presents unique risks due to their specific properties.
How Water Becomes Radioactive
Can water be radioactive? It's a complex process, but let's break it down. Nuclear power plants like Fukushima, which are crucial for meeting our energy needs, may present local and global concerns when it comes to how they use water in their process.
The production of nuclear energy involves the splitting of unstable atoms that release radiation. During this process, cooling water comes into contact with these materials and becomes contaminated. Real-world effects can arise if proper management is not implemented.
Tritium Levels in Water
A significant factor in the radioactivity of water is Tritium. This radionuclide exists naturally but also increases significantly near nuclear facilities due to its production during nuclear reactions.
- Increased tritium levels indicate higher radioactivity - something we need to closely monitor around nuclear installations.
- Tritiated water (water containing tritium) can be easily absorbed by organisms, leading to potential health hazards over time if ingested or exposed externally.
- Radiological safety heavily relies on effectively managing these risks - monitoring tritium levels helps us achieve that.
The Challenge We Face Today
We must strive to maintain an equilibrium between our trust in nuclear energy and the urgent requirement for pure, secure drinking water. As technology advances and demands increase, so does the complexity of managing radiological safety in relation to the abundance of radionuclides in waters near power plants.
Radioactive Water Treatment & Safety Zones
The treatment of radioactive water, a puzzle that scientists have been striving to solve for decades, has found its solution in advanced liquid processing. But what about tritium levels?
Tritium is an isotope of hydrogen and it cannot be removed from waters completely. The key lies not in elimination but dilution. In essence, international safety standards are our guiding light here. These stringent rules ensure negligible radiological impact when treated water is released back into nature.
Tritium Dilution Process
Treating radioactive water involves careful management and balancing of tritium levels before releasing them into the ocean. It starts with diluting the tritiated water with large volumes of regular, non-radioactive water. This reduces its concentration below operational limits set by regulatory bodies like IAEA (International Atomic Energy Agency).
Tests conducted on Japan's nuclear plants' discharge show, according to BBC news, “It was treated to remove all radioactive elements, except tritium which is very difficult to remove. The water was diluted to reduce radioactivity to 1,500 becquerels per litre, far below the drinking water standard of 10,000 Bq/L.”. If done right, such diluted releases pose no harm to marine life or humans.
Safe and Unsafe Levels
According to the United States Nuclear Regulatory Commission, the standard for safe tritium contamination levels is 20,000 pCi per liter (pCi’s being units of measurement for radioactivity). Determining if a water source is within these recommended limits requires in-depth professional lab testing. In the case of the Fukushima radioactive water, we can only hope that proper measures are being taken to ensure the water remains within that safety zone. We must also keep in mind that though these levels are labeled “safe” there is still a somewhat broad window left open for potential risks to aquatic and human life.
Health Risks of Radioactive Water
Especially in cases where the proper precautions and procedures are not adhered to, radiation in water is not only a menace to aquatic creatures, but also poses serious risks for people.
The tritium in radioactive waste water even when diluted, can cause damage over time when ingested, inhaled, or absorbed through the skin. Safe levels of tritium exposure have been determined and updated, but the word “safe” in this situation may just mean a reduced risk and not the absence of any risk at all.
What Consistent Exposure To Even Safe Tritium Levels Will Do
Though a drinking water source isn’t directly in question in the particular case at Fukushima, for individuals and households whose water is supplied by a source that has been contaminated by radioactive particles, this puts them in a position where they are exposed little by little each day to the trace tritium. This then increases their chances for cellular sickness such as mutations and cancer.
Environmental Impact Of Radioactive Water
In this particular case however we would take into consideration moreso the sealife, and potential exposure to humans through eating local seafood or swimming in these exposed waters. This leaves a much smaller window for risk to human health, but the sea life may not fair so well over time.
No matter the exact situation, when radioactive substances enter our bodies in small doses over time, there is an increased likelihood of health risks. Radioactive water even in consistent daily doses may cause damage to or kill cells, whether in humans or in nature.
Keeping Your Drinking Water Safe
While radioactive water often causes more global concerns, the average household is still at risk of exposure to chemicals, heavy metals, and other harmful water contaminants, in addition to the radioactive tritium previously mentioned.
If you want to ensure your household drinking water is as safe as possible, one step in the right direction is considering the use of a specialized reverse osmosis filter. As #1 manufacturer in the U.S. of Reverse Osmosis Systems, APEC’s top-of-the-line water filtration systems make sure your tap delivers safe and clean drinking water every time.
