For the types of radiation that you would typically use lead as shielding for a layer or two of lead paint would be useless. It would be more likely to give you lead poisoning than provide any effective protection from radiation.
As harryk says above, the primary hazard for people around Chernobyl and Fukushima is un-fixed contamination, so radioactive dust and contaminated water.
 
Mars would be rather different - as the planet doesn't really have a magnetic field any more there is very little protection from cosmic rays (X-rays and gamma) and even UV radiation from the Sun. On Mars it may well be worthwhile having buildings incorporating heavy duty radiation shielding (if you want them on the surface) - but shipping the materials to the planet would be very expensive given their weight, or they would have to be manufactured in place once you got there (which may be practical for something like concrete). A simpler solution would be to live underground (provided the rock you were digging into wasn't itself radioactive or presenting other toxicological hazards (like heavy metals).

That quote pops up in Civilization VI for one of the science techs (Animal Husbandry I think).
Very true it is too.

Okay:
5g NaOH = 5/40 moles = 0.125 moles NaOH (in 120mL = 1.042 moles/L)
200 mL of 0.2M HNO3 = 0.2moles/L x 0.2L = 0.04 moles HNO3
You can ignore the Na+ and NO3- counter ions.
H+ + OH- -> H2O
The OH- is in excess so effectively 'all' of the H+ is neutralised so your final OH- concentration is 0.125 - 0.04 moles = 0.085 moles
You have 0.085 moles of OH- in 320mL of water so you [OH-] = 0.085 moles/0.32L = 0.265625 moles/L
 
pOH = -log10 (0.265625) = 0.5757
 
14 = pH + pOH
pH = 14 - pOH = 14 - 0.5757 = 13.4243 or about 13.4

pH = 14 - pOH = 14 - 0.5757 = 13.4243 or about 13.4

Both components are 'strong' so you don't have to worry about the ionisation potential of either - it would be different if you had something like acetic acid or ammonia for example.
 
pH is the -log (to the base 10) of the Hydrogen ion concentration
It's counterpart, pOH is the -log (to the base 10) of the Hydroxide ion concentration.
The sum of pH and pOH is 14 so once you know the concentration of one of the ions you can work out the rest.
 
You said you had worked out the concentrations - the acid will have been completely neutralised as the NaOH was in excess. Whatever your final NaOH concentration is also the OH concentration so you can calculate the pOH value then subtract it from 14 to get the pH. I got a pH of ~13.4.

Ah dog farts.
My old dog Tom (also a Collie) once released a guff while lying in the middle of the livingroom. He raised his head to look at his own backside and decided that was good time to leave the room - even he didn't like his own brand (at least that time). Suffice to say the rest of the room occupants got hit with it just after he'd slinked out the room.

This would be my Border Collie, Jodie. She is around 6 years old.

Dogs have owners, cats have staff.
 
In other news, this is Glen, my parents dog:
His propensity for enjoying playing with rocks has had an adverse effect on his teeth (of which he has few left), hence the sticky out tongue. The disaster that are his teeth don't seem to bother him as he really likes chewing up ice cubes.
In his younger days he had a habit of periodically receiving new instructions from the mothership (he'd stop dead and start at the lights in the livingroom for a few seconds then go on about his business).
Border collie in case you can't tell.

For I too am a ginger scientist!

The Mercury S8 was the only case I wanted to upgrade to from my HAF XB Evo, and I've been planning it for a long time. Now that I'm so close to finally having the means, Caselabs suddenly dies.
... I am not okay with this.
 
I guess I could look at Protocase, or maybe just look into making my own, because no other company seems to make such a well-built and clean horizontal motherboard ATX case. The entire goddamn industry seems oriented directly against what I want, and the one small company that satisfied my niche perfectly now no longer exists.
I am really not okay with this.

The first CPU and GPU I owned in a computer I bought myself was a PowerPC G3/233 augmented by I think and ATI Rage 128.
Only got rid of it this year.
The first computer my brother and I acquired was a Sinclair 48k Spectrum, so, whatever was in that.

Provided you avoid they shadier parts of the interweb and don't do stupid stuff like clicking on random links in e-mail from people you haven't heard of before the antivirus built into Windows 10 is perfectly adequate (It's what I use). If you want additional protection then Malwarebytes would be a good addition.
The main thing to remember is that no antivirus solution is perfect - all it takes is a bit of bad luck (or stupidity) and a zero day exploit and your AV software is unlikely to stop the malicious code. Pick whichever AV meets your needs in terms of cost, convenience and system impact (AV software can be a bit of drag on system resources if its not well written).
 
In addition to AV you should also look at backing up your data on a regular basis - get an external hard drive or two and set up a backup regime (there is backup software built into windows or other options). Provided your data is backed up and secure you've got a fall-back position if some malware does manage to get through whatever your using.

I actually asked a dietitian this question once. When you eat makes no difference in terms of weight loss or gain, it's what and how much you eat that matters.
What eating late at night (or rather before going to bed) can do is give you issues getting to sleep and you may be more susceptible to things like acid reflux while you're digesting your food if you're lying down. Basically, you'll probably find it easier to get to sleep if your stomach isn't churning away trying to deal with what you've just eaten.
