ONLY SMOKERS GET LUNG CANCER


Fact: Anyone can develop this disease, though current and former smokers are at a higher risk.

As many as 20 per cent of the people who die of lung cancer do not smoke or use any other form of tobacco. Some of the other risk factors include:

Radon gas: This gas occurs naturally outdoors in harmless amounts, but it can get trapped in houses and buildings. Studies have found that lung cancer risk is higher in those who have lived for many years in a radon-contaminated house.

As radon gas is an odourless gas that cannot be seen, the only way to know whether it is a problem in one's home is to test for it. Unfortunately, we do not have data on radon levels in Singapore.

Second-hand smoke: Each year, an estimated 7,000 adults die of lung cancer as a result of breathing in second-hand smoke. Laws that ban smoking in public places have helped to reduce this danger.

Cancer-causing agents at work: Some workplaces can expose one to carcinogens or cancer-causing agents, like asbestos and diesel exhaust. If you work around these agents, you should limit your exposure whenever possible.

Air pollution: It has long been known that both indoor and outdoor air pollution contribute to lung cancer. In 2013, the World Health Organisation classified outdoor air pollution as a carcinogen.

PS. It is not only haze that increases the risk of lung cancer (very very low), but rather the annual PM2.5 exposure. The risk for heart attacks, heart diseases like ischemic stroke is relatively much much higher vs lung cancer for the levels we experience here. (you gotta go to Indonesian cities like Palembang/Palangkaraya to have a good spike in risk for lung cancer). But do not compare Singapore's biomass haze vs China's smog, concentration ug/m3 for ug/m3, China's smog is much higher risk due to heavy metals found there like arsenic, cadmium etc.


PPS. EPA has done a big study with regards to cancer risk of wood smoke vs diesel exhaust smoke. The lung cancer risk is 3X that of wood smoke at the same concentration. Fortunately, at present we don't have a big issue with diesel exhaust smoke due to the latest Euro standards (other countries are Euroless or Euro II at best). But maybe you'd still take note if you live beside an expressway, eg Sims Drive just 40m from PIE.


i believe IARC #161 states it all :) https://www.iarc.fr/en/publications/books/sp161/AirPollutionandCancer161.pdf

speaking of radioactive stuff, one of my clients who's a geomancer told me that amethyst um, crystals (those humongous ones) MAY be radioactive - so it MAY be a case of poisoning oneself.... and hence he does not advise his clients to get it - and neither does he.

So I can stick it close to the wall?
The backside where the filter is exposed will do?
Should place close to air con or window?

Download the Eng manual for reference bro, got recommended clearance of 15cm :)

Don't need to be purposely near air con or window. Anywhere where it can circulate the air well is best. I put mine on a nightstand next to the bed so the filtered air nice nice blow over us when sleeping, lol :o

For living room it is near one of the corners due to furniture placement, but I have ceiling fan blowing in the middle to circulate, so all the air should eventually get filtered fast enough.

This is for the SG version I think, so diff model number, other than that should be similar.

dont stick the back facing on the wall. thats where it suck in the air. leave a gap

put it opposite your aircon with the outlet facing ur aircon to create circulation.

If i'm not wrong, what it's saying is if the filter back side face the wall, should have 15cm clearance.
If the back side face out, don't think still need right

Those ordering from taobao the cheap hepa for ax40.
The seller says order nine can fit just nice to one medium size carton.

My ax40 from qoo just arrived, the first one bought from this seller call daiso.
The Goni seller haven even ship yet.

So I can stick it close to the wall?
The backside where the filter is exposed will do?

This hepa is for the 25mm thickness or the 45 mm thickness?

I'm definitely not an expert in radioactivity/nuclear science, but what I know
is that the few types of rocks on earth, like igneous and metamorphic rocks.....we only have 2 types of naturally occurring radioactive isotopes in them, that's uranium and thorium. Very very minute amounts, ppm.

The thing about radioactivity poisoning in humans is basically that we must (1) ingest or (2) inhale these radioactive particles so that they are lodged right next to our tissue cells and possibly getting those particles past the lung and intestine epithelium cells into our blood and hence transferred and concentrated at the various organs like liver, kidneys and whatnots. For inhalation, a certain PM size may mean that they can be lodged there.

So what happens is that by then even an ultra ultra minute amount can cause harm coz these minute particles are right next to our cells and the most harm is done by alpha ionizing radiation which is the most energetic of them all.

If we touch this radioactive PM, nothing will happen. Our skin would block the alpha radiation. The uranium in igneous/metamorphic rocks are really in low amts anyway. So any gamma radiation would be low, something like cosmic background levels.

http://ieer.org/resource/factsheets/uranium-its-uses-and-hazards/

Uranium-238 emits alpha particles which are less penetrating than other forms of radiation, and weak gamma rays As long as it remains outside the body, uranium poses little health hazard (mainly from the gamma-rays). If inhaled or ingested, however, its radioactivity poses increased risks of lung cancer and bone cancer. Uranium is also chemically toxic at high concentrations and can cause damage to internal organs, notably the kidneys.


So basically, it's just uranium decay and getting radium/radon gas, which further decays into daughter products of polonium (polonium-218) which would stick to our lint/dust whatever......and then we breathe them in. Polonium is extremely extremely toxic.

This is not Polonium-218, but Polonium 210's toxicity.

And Polonium-210 is found in tobacco smoke. :s13:

https://en.wikipedia.org/wiki/Polonium

Tobacco[edit]

Polonium-210 in tobacco contributes to many of the cases of lung cancer worldwide. Most of this polonium is derived from lead-210 deposited on tobacco leaves from the atmosphere; the lead-210 is a product of radon-222 gas, much of which appears to originate from the decay of radium-226 from fertilizers applied to the tobacco soils.[47][110][111][112][113]

The presence of polonium in tobacco smoke has been known since the early 1960s.[114][115] Some of the world's biggest tobacco firms researched ways to remove the substance—to no avail—over a 40-year period. The results were never published.[47]

Food[edit]

Polonium is also found in the food chain, especially in seafood.[116][117]
Edit by Wuss - that's why never ever eat the big end-of-the-food-chain fishes like Shark/Tuna as if there is no tomorrow, eg 1 can per day is a sure way to uplorry. Sardines are good though with many benefits that outweigh any ultra minute risks, coz it's a small fish.

What happens when you inhale polonium?

Polonium-210 emits a type of radiation called alpha-radiation, which is very energetic and can seriously damage DNA. Thankfully, what alpha-radiation has in destructive ability, it lacks in penetrating power. Human skin is usually enough to stop it, but that’s of little consolation to people who inhale particles of polonium-210. That places the tissues of their lungs and airways in direct and close contact with these powerful sources of radiation.

Indeed, studies have detected polonium-210 in the airways of smokers, where they are concentrated in hot spots. They remain there because other chemicals in cigarette smoke damage the body’s cleaning systems, which would normally get rid of gunk in our airways.

As a result, polonium builds up and subjects nearby cells to higher doses of alpha-radiation. These localised build-ups lead to far greater and longer exposures to radiation than people would usually get from natural sources.

For example, one study found that a person smoking two packs a day is exposed to about 5 times as much polonium as a non-smoker but specific parts of their lungs could be exposed to hundreds of times more radiation. Another study estimated that smoking a pack-and-a-half every day exposes a smoker to a dose of radiation equivalent to 300 chest X-rays a year.

Do these doses lead to lung cancer? It’s hard to say, especially since the effects of polonium are only part of a wider range of damaging consequences caused by inhaling cigarette smoke. But animal studies certainly give us cause for concern.

Absorbed doses of radiation can be measured using units called rads, and experiments have shown that as little as 15 rads of polonium can induce lung cancers in mice. That’s only about a fifth of what a smoker would get if they averaged 2 packs a day for 25 years. Indeed, the lung tissues of smokers who have died of lung cancer have absorbed about 80-100 rads of radiation.
