Happy birthday to #physicist Harriet Brooks (1876 - 1933) who discovered atomic recoil, Radon & recognized radioactive elements could undergo chains of transmutations into a series of new elements. #nuclear #physics
She was Rutherford’s 1st grad student at McGill. After publishing her results in 1899 she completed her MSc in 1901 on “Damping of Electrical Oscillations,” before embarking on #radioactivity research.

A favorite of mine, Windy.com -- which has had significant upgrades!
"In 2021, two new #ICON forecast models were integrated - ICON-D2 with local coverage for central and west #Europe and ICON Global. Thousands of new air quality stations monitoring primary pollutants worldwide were added from our partners #OpenAQ and #PurpleAir to fight #AirInequality.
"Several new layers were launched - Tidal currents featuring high-resolution data; the Sea currents dataset was updated; Thermals layer with soaring forecast for glider and paraglider pilots; Drought monitoring layers - Soil moisture, Moisture anomaly, and #Drought intensity, monitoring global drought.
"We also expanded into the wear OS category and introduced Windy Apple Watch App. The 3D Globe mode was brought back for most layers (desktop only), including the Hurricane Tracker.
"In 2022, we launched several new features and improved existing ones. In the beginning of the year, we added a new #radioactivity set of stations as a POI overlay and partnered with SaveEcoBot, run by a non-profit organisation SaveDnipro, and obtained a broad spectrum of environmental data sources in #Ukraine and offer them in an easy-to-access way to our users and other affected communities for free.
New local models HRRR for the US and ACCESS model for Australia were added, along with a set of layers wet-bulb temperature, UV Index and Solar power.
With release of iOS16, the Windy.com iOS app got LockScreen widgets, which can be placed on the phones's locked screen. A new significant iOS feature.
"For the #HurricaneSeason, we launched redesigned and upgraded our Hurricane Tracker and added multimodel forecast & LIVE satellite visualization. Users in the US could also appreciate an improved radar resolution and coverage."
Things going through my mind right now:
If you surround explosives with radioactive material, you get a dirty bomb.
When you detonate bombs inside an enrichment factory and storage of radioactive material, the effect is essentially the same, isn't it?
So... how far will Uranium hexaflouride and other precursors be carried by air?

"Marie Curie worked here from 1914 until 1934, the year of her death, handling radioactive elements including radium, which she and her husband Pierre Curie had discovered in 1898. For most of her life, she did this with bare, increasingly radium-scarred hands. She then transferred traces of these elements onto other things she touched."

I may be loonatic, but to the best of my knowledge, the idea that managing nuclear waste safely over hundreds of thousands of years is impossible and that all containment inevitably fails within a century is not supported by current scientific understanding and technological progress.
1. Multi-Barrier Approach and Container Longevity
Modern nuclear waste disposal relies on a multi-barrier system combining engineered containers, buffer materials, and stable geological formations. While individual containers may degrade over centuries, the overall system is designed so that multiple layers provide overlapping protection for much longer periods. For example, copper or steel canisters used in deep geological repositories are engineered to resist corrosion for thousands to tens of thousands of years under repository conditions. [1][2]
2. Geological Stability and Site Selection
Deep geological repositories are sited in geologically stable formations, such as crystalline bedrock or clay formations, chosen for their minimal seismic activity and tectonic stability over geological timescales. While tectonic plates do move, repository sites undergo extensive geological assessment to ensure stability for at least hundreds of thousands of years, mitigating risks of disturbance. [2][3]
3. Proven and Developing Technologies
Countries like Finland and Sweden have advanced repository projects (e.g., Onkalo in Finland) that demonstrate the feasibility of safe long-term disposal. These repositories are designed to isolate high-level waste for up to a million years, with scientific consensus supporting their safety and environmental soundness. [4][5][6]
4. Misconceptions about Chernobyl’s Sarcophagus
The Chernobyl “second dome” was an emergency containment structure designed to limit radioactive release after an accident, not a long-term waste repository. Its challenges do not reflect the engineered, purpose-built deep geological disposal facilities designed for nuclear waste management.
5. Radioactivity Decay and Waste Hazard Reduction
The radioactivity and heat output of high-level waste decline significantly over time. After about 40–50 years in interim storage, waste radioactivity drops to a fraction of its initial level, making handling and disposal safer. This decay process is a key reason for the interim storage period before final disposal [4][6]
I’m not asking you to simply believe me; I’m just asking you to consider that I am trying to follow the facts wherever they lead. I have no emotional or personal preference for or against nuclear energy. Please, if you have sources that contradict my information, share them with me so that I can reconsider my informed opinion.
To the best of my knowledge, managing nuclear waste safely over very long timescales is a complex but well-studied challenge with scientifically validated solutions.

Hi @silkester
Could you please clarify what exactly you mean by "stuff"? If you intend to provide information about radioactive isotopes in the 'my body', it would be much more helpful if you could also share the sources of your information. That way, I can verify and better understand your claims.
If you are referring to naturally occurring radioactive isotopes in the human body, I must point out that there are some common misconceptions about their sources and nature.
Naturally Occurring Radioactive Isotopes in the Human Body
The main naturally occurring radioactive isotopes present in the human body are:
Carbon-14 (C-14): This isotope is produced naturally in the atmosphere by cosmic rays interacting with nitrogen. It becomes part of the carbon cycle and is incorporated into all living organisms, including humans. Carbon-14 has a half-life of about 5,730 years. [1][2][3]
Potassium-40 (K-40): Potassium-40 is the most significant naturally occurring radioactive isotope in the body. Potassium is essential for many biological functions, and about 0.0117% of natural potassium is potassium-40. It has a very long half-life of approximately 1.25 billion years. [4]
Both C-14 and K-40 are naturally occurring isotopes and are generally not human-made, except for minor artificial increases in C-14 levels due to atmospheric nuclear bomb testing during the mid-20th century. However, since the end of atmospheric nuclear testing, the biggest source of human-generated radioactivity is now largely from the burning of fossil fuels, particularly coal, which releases naturally occurring radioactive materials trapped in the earth. [5][6]
Additional Points on Radioactivity and Sources
Radioactivity is a natural phenomenon and is not produced by humans. Elements like uranium and thorium are radioactive whether found naturally in rock formations or used in human-made reactors
Trace amounts of uranium, thorium, and their decay products (such as radon gas) are also present in the human body, primarily absorbed from food, water, and air.
Nuclear energy has not contributed significantly to environmental radioactivity compared to natural sources and fossil fuel combustion [6]
I would appreciate it if you could cite your sources, as it is difficult to follow and verify your argument without references. Reliable citations help ensure the accuracy and validity of information, especially on complex topics like radioactivity.
