Welcome to my Environmental A-Z…today it’s the letter R…I have been unable to find anything beginning with the letter Q…I have also been heartened to hear how many of you feel like I do that we need to take our own steps to avoid pollution wherever we can…
Abraham Lincoln is correct we need to act now to create the future for our families that we want…but at the moment we can only dream of…
The best way to predict your future is to create it...Abraham Lincoln.
The A-Z of the environment and Climate Change… letter R( No) Q…
Radon is a naturally occurring radioactive gas that can cause lung cancer. Radon gas is inert, colourless and odourless. Radon is naturally in the atmosphere in trace amounts. Outdoors, radon disperses rapidly and, generally, is not a health issue. Most radon exposure occurs inside homes, schools and workplaces. Radon gas becomes trapped indoors after it enters buildings through cracks and other holes in the foundation. Indoor radon can be controlled and managed with proven, cost-effective techniques.
Breathing radon over time increases your risk of lung cancer. Radon is the second leading cause of lung cancer in the United States. Nationally, the EPA estimates that about 21,000 people die each year from radon-related lung cancer. Only smoking causes more lung cancer deaths…to read the full report please click this link.
Indoor radon is a preventable risk factor that can be handled through effective national policies and regulations.
This is the report from the World Health Organisation(WHO)
Personally, I have never been aware of any national policies surrounding this…Have you?
Renewable resources are an energy source that cannot be depleted and are able to supply a continuous source of clean energy.
Currently, these are the most popular resources…
- Solar energy…Sunlight is one of our planet’s most abundant and freely available energy resources. The amount of solar energy that reaches the earth’s surface in one hour is more than the planet’s total energy requirements for a whole year. Although it sounds like a perfect renewable energy source, the amount of solar energy we can use varies according to the time of day and the season of the year as well as geographical location. In the UK, solar energy is an increasingly popular way to supplement your energy usage.
- Wind energy…The wind is a plentiful source of clean energy. Wind farms are an increasingly familiar sight around the world with wind power making an ever-increasing contribution to the National Grids. To harness electricity from wind energy, turbines are used to drive generators which then feed electricity into a National Grid. Although domestic or ‘off-grid generation systems are available, not every property is suitable for a domestic wind turbine.
- Hydro energy…As a renewable energy resource, hydropower is one of the most commercially developed. By building a dam or barrier, a large reservoir can be used to create a controlled flow of water that will drive a turbine, generating electricity. This energy source can often be more reliable than solar or wind power (especially if it’s tidal rather than river) and also allows electricity to be stored for use when demand reaches a peak.
- Tidal energy…This is another form of hydro energy that uses twice-daily tidal currents to drive turbine generators. Although tidal flow unlike some other hydro energy sources isn’t constant, it is highly predictable and can therefore compensate for the periods when the tide current is low.
- Geothermal energy… By harnessing the natural heat below the earth’s surface, geothermal energy can be used to heat homes directly or to generate electricity. Although it harnesses power directly below our feet, geothermal energy is of negligible importance in the UK for example compared to countries such as Iceland, where geothermal heat is much more freely available.
- Biomass energy…This is the conversion of solid fuel made from plant materials into electricity. Although fundamentally, biomass involves burning organic materials to produce electricity, and nowadays this is a much cleaner, more energy-efficient process. By converting agricultural, industrial and domestic waste into solid, liquid and gas fuel, biomass generates power at a much lower economic and environmental cost.
With a few available options, I am wondering why we are still burning fossil fuels as they are not renewable and will run out…Plus they release Carbon Dioxide into the atmosphere which contributes to Climate Change and Global Warming…Just asking!
Thank you for joining today for my environmental A-Z…See you tomorrow in my kitchen for more potatoes to finish of National Potato Month…xxx
