Only glowing with Potassium-40.
Radiation dose, this is not an individual estimate but typical average*: CT head 2 mSv, CT Abdomen about 8 mSv, Chest X-ray 0.1 mSv if it included a lateral view. Mammo not my thing, but a paper says 0.4 mSv. 10.5 mSv all up. About the same dose as 157 flights MEL-SIN-LHR. Strangely enough it would be 241 trips LHR-SIN-MEL.

Do you want to know the risk?

* insert other disclaimers such as this is not individual financial advice, etc...
Perhaps include the radiation dosage from ADL/MEL-LHR return?

lol
good point.
I got the flight dose data from here: ARPANSA - Flying and Health: Cosmic Radiation Exposure for Casual Flyers and Aircrew
Aside from the route specific information. That also has hours at particular altitude at latitude 30 degrees South. Which is roughly Adelaide Melbourne. Based on that about 200 to 300 hours to get 1 mSv.

they also link to the Cari-6 model which allows you to calculate dose for any given route and date, provided you have some basic flight profile information.

Flight profile information can be found on Flightaware going back about 2 weeks for free. The Cari-6 model is currently only up to date until Jan/2016. This is because the model requires sun activity data, I assume that takes a little bit of time to process

Anyone suggest a way to stop cooking smells and other household smells? A normal face mask such as those worn by doctors/nurses is not enough.

Something like this with appropriate filter pack. I'd guess at least the organic filter pack, or perhaps a charcoal filter. I'm not sure exactly, you can do the research. But not just a particulate filter, as you've discovered those don't stop smells.

Given that odours are an integral part of cooking and life itself, the only thing I can reasonably suggest is industrial scale extractor fans above the stove, above the kitchen and throughout the house. But the trade off would be that you'd have to glue down everything that weighs less than a kg and that cheese you sprinkle on a dish will get sucked straight up and not reach the plate - but at least you wouldn't smell it.

Hardly reasonable. They won't need to move industrial quantities of air. Also unlikely to get permission to modify an apartment building to install the required ductwork and stack to vent to atmosphere. No, indeed PPE is the only reasonable option.

Perhaps even something like this...

Yes, I guess you are right about the apartment permissions (I wasn't aware of the exact living situation). But given the speed at which volatile molecules move and the quantity (that's expressed in my layman's terms!), you'd have to have a fair old movement of air between one's nose and the pot or the chair to prevent smelling the object. Maybe this is the answer, without the foot and hand coverings, but the rest is probably necessary to properly seal off the head (nose) and maintain the external air supply purity.

When it comes to eating, I guess the food would have to be liquefied and taken via a straw directly into the mouth, to prevent odour reaching the nose.

Understood. Occasionally the odours can cause headaches and nausea for someone that is sensitive to these odours. This is a temporary measure not long term. Have tried normal face masks and fans. Odours have a way to get past. And the odours are not necessarily local but from other households.

And you don't realise how bad those odours can be until it happens to you. Walking home on Milton Road last night. Crossed the road and this cooking odour started choking me. I can assure you it was not a pleasant odour. The nearest house/kitchen had to have been 20-30 metres away if not more.

Respirators with an activated cartridge will stop smells - is it for you JohnK? I have see you mention that you get claustrophobic and couldn't wear a Cpap mask so a respirator may not be practical unless it is for someone else (I have not been following - just noticed "Filter Pack" and "organic" and it caught my eye)
