What Are the Potential Dangers of Nuclear Melt and Its After Effects?

In summary, there are several other significant radioactive isotopes with varying half-lives and potential dangers to consider, such as Sr-89, Cs-134, Pm-147, Sm-151, and Kr-85. These isotopes can form oxides and be carried away by air or water, and may have varying levels of volatility. The key factors to consider are their yield and half-life, and they are considered persistent in the environment. More information can be found in the linked sources.

Are there any other measurable danger other than the following


Short term (short half life)

I -131
Do not react with air
Forms aqueous solution with water


Long term (long half life)

Cs -137
Forms cesium oxide with air, can be carried away by air
Forms aqueous solution with water

Sr - 90
Forms strontium oxide with air, can carried away by air
Forms strontium nitride with air, can carried away by air
Forms aqueous solution with water


Not sure if there are any other major concerns

According to http://en.wikipedia.org/wiki/Fission_product_yield
there a few more significant isotopes

Sr-89 - half-life 50d
Cs-134 - 2 years
Pm-147 - 2.6 years (how volatile is it?)
Sm-151 - 90 years (how volatile is it?)
Kr-85 - 10 years (as a noble gas, it disperses quickly, doesn't stay in soils or living tissue)

Pm and Sm would preferentially form oxides, as do the other rare Earth's.

Cs is volatile, as is I, and Sr, is somewhat volatile and soluble.

Kr-85 is a gas, so it could more readily escape containment.The key is yield and half-life. The OP states the 3 key radionuclides since they are persistent in the environment.

1. What causes a nuclear meltdown?

A nuclear meltdown occurs when the core of a nuclear reactor overheats and the fuel rods begin to melt. This can be caused by a loss of coolant, a power failure, or a malfunction in the reactor's cooling system.

2. What are the immediate effects of a nuclear meltdown?

The immediate effects of a nuclear meltdown can include a release of radiation and the generation of intense heat. This can lead to the destruction of the reactor and surrounding structures, as well as potential harm to nearby populations.

3. How long do the after effects of a nuclear meltdown last?

The after effects of a nuclear meltdown can last for decades or even centuries. The radiation released can contaminate the surrounding area, making it uninhabitable for humans and wildlife. The cleanup and recovery process can also take a significant amount of time.

4. What are the long-term health effects of a nuclear meltdown?

The long-term health effects of a nuclear meltdown can vary depending on the level of exposure to radiation. Acute radiation sickness, cancer, and other health issues can occur in those who were directly exposed to high levels of radiation. There can also be long-term effects on the environment and food supply.

5. How can we prevent or minimize the effects of a nuclear meltdown?

The best way to prevent a nuclear meltdown is through strict safety regulations and regular maintenance of nuclear reactors. In the event of a meltdown, evacuation and containment measures can help minimize the effects on surrounding areas. Continued research and development of safer and more sustainable energy sources can also reduce the risk of future nuclear disasters.
