Rest with roses

We’ve had several beautiful sunny days giving some promise of a true spring but the nights have been so freezing that progress has been minimal. The snow bed is hard and almost knee high everywhere around our place, which isn’t that bad for outdoor activities.

However, I’ve had to stay indoors because of some problems with my leg. I’ll tell more about that later, although sitting too many hours by the computer without taking proper pauses certainly didn’t help. Such carefree behaviour will defeat you eventually. So I’ve spent the last few days moving around from room to room and from sofa to sofa carrying with me the bunch of roses I bought on Saturday. If you have to lay low you’ve got to take whatever pleasure there is for you to take.

By bright light

Further to my post of yesterday, I can hear someone saying, “But what about bright light therapy?” Indeed, what about that? We do have a bright light lamp. It is one of the two devices we bought before Christmas as sort of presents to ourselves hoping they would help us endure winter we’ve found so hard to stand in recent years. The other one was the snow blower that’s now proven far more cumbersome than we expected, not actually a facilitator.

In contrast, mastering bright light therapy is easy as ABC. First, you introduce bright light into your daily schedule with sessions of at least 30 min; that is, you stay by the lamp for half an hour to get the effects going. Thereafter, an exposure of a mere 15 min daily should be enough to alleviate your symptoms of winter blues or even cure them altogether.

However, there is one shortcoming in this form of therapy: it is most effective when administered in the morning, preferably before 9 (or 10) am. A medium to wake me up and take me downstairs before 9 (or even 10) in the dark season – I tend to do some arranging upstairs, often for an hour or so, before descending to have my ‘breakfast’ – is yet to be discovered!

Luckily, I was farsighted enough to choose a dimmable bright light lamp that can serve also as an ordinary table lamp thus ensuring this purchase will not be completely wasted even if I were too lazy to utilize its potential. And there will be other winters soon enough, I’m afraid.

At least my daughters Maine Coon princess Sheena took the most of the lamp during her Christmas holiday with us. Sheena is such a nosy lady anything new and different fascinates her unlike her ‘brother’ who tries to keep cool whenever the ladies fuss about something. 

By the way, the news just confirmed what I’ve been feeling: we’ve had only 50 hours of sunshine in southern Finland since the beginning of December as opposed to 80 last year and 92 the year before that. This has, indeed, been the cloudiest winter in 25 years here.

Better safe than sorry

I’d like to remind everyone living in an older house about the importance of measuring the indoor radon levels to see whether any improvements are required to lower the concentration of this radioactive gas in your home.

If your house was built before your local building regulations included radon protection, especially if you happen to be living in a risky area but are unaware whether any protective insulation or ventilation has been carried out since, now is the time to order a home measurement kit from your local authorities.

The measurement must be made for at least two months during the cold season so this is the time for the northern hemisphere. We made it last season and are safe. Everything I discovered last year about this cancer-causing gas, how to measure it in your home and where to find maps to give you an indication about radon levels in your area can be found in my post here. Let’s hope you will be safe, too.

How about your radon levels?

When you live in a ‘house with character’ there will always be something to worry about. One odd corner or another of your old cottage will always be in need of some cleaning, painting, fixing or another, more thorough form of shake-up. I generally leave the worrying to my husband but there’s been one question that’s been a concern to me rather than him: how much radon do we inhale annually?

Radon is a cancer-causing radioactive gas that cannot be detected by any of the human senses. It is created by the natural breakdown of uranium in soil, rock and water and it moves up through the ground to the air we breathe. If the foundation of a building that happens to be located in a risky area is not properly radon-protected by ventilation or insulation, the gas will enter your home and, in the case of insufficient indoor ventilation, it may remain trapped there causing health-threatening radiation levels.

Finland has a population of some 5.4 million but even here it is estimated that radon causes some 300 deaths from lung cancer annually. In the UK where the average radon level is lower, the figure is 1,100 and in the USA as many as 21,000 people die annually because of it. That is certainly reason enough to have your house ‘radon-detected’ if you are in doubt.

According to the Finnish Radiation and Nuclear Safety Authority (STUK), our indoor air radon levels are the highest in Europe and probably in the whole worlds. This is because of our geology, construction technology and climate. Our rock and soil are of granite and richer in uranium than the average around the globe. The highest concentrations are found on sand and gravel ridges as it is easy for the gas to rise through them. Moreover, radon levels are generally the higher the colder the weather is. That is why the measurement must be made during the cold season.

In our country, the building regulations have instructed at least since 1992 to take radon into account in the design and construction of all new buildings. The situation is most likely rather similar elsewhere, too, as well as that for the older houses: you will find some indication from the radon maps published by the authorities (e.g. STUK in Finland, the Health Protection Agency in the UK and the Environmental Protection Agency in the USA) but the only sure way to know is to measure.

So we ordered a home measurement kit from STUK. The detector is a small black plastic canister with a polycarbonate film inside and a few holes on the top for the radon to penetrate. The radiation will leave marks that can be analysed from the film in a laboratory. One detector costs about 43€ including the analysis and report (the current UK price is approx. 50£).

In smaller apartments one detector is enough but in larger ones at least two are required. If your house has several floors the detectors should be placed in the ground floor (not the basement unless someone lives there) and in the first (and every other) floor at the height of about one metre and kept on the same spot for at least two months, preferably three.

We let the detectors be from the end of November until the end of February, then posted them to STUK and less than two weeks later we were safe. The results revealed radon levels far below the national action level of an annual average of 400 becquerels (Bq) per cubic metre of air, even considerably lower than the target level of 200 Bq and even lower than the target level of 100 Bq recommended in some other, less ‘uranium-rich’ countries such as the UK.

Our readings were 90 in the downstairs living room where the hard wood floor has never been removed to see what’s beneath since it was built probably in the late 1930s or early 1940s, and 80 in the upstairs hall in the older part of the house that has been completely rebuilt.

Had the concentrations been higher, I – for once – would have had a plan. The easiest way to get rid of this dangerous gas in older buildings it to install a radon fan down through the basement to suck the radon from under the house and pipe it up either through the roof or out-of-doors by the side of the house.

Our electrician recently told he had built and installed a radon fan for his house at the cost of less than 100€ but he is a professional in electrical installations. I guess for a layman the cost for a ready-made appliance and its installation would be a few, say 10 times more but even if it were 20 or 30 times more that is nothing for eliminating one deadly carcinogen from your daily life.

Radon can also enter your home through well water if you have a drilled deep well. Luckily our well is built on a natural spring so we do not have to worry about the well, at least as regards radon.
