Assuming that you're standing exactly at solar midnight, exactly on the opposite side of the planet as the sun, and all 100 trillion neutrinos are coming from the sun and through your 1.8 meter height, each neutrino will be in your body for 6 x 10^-9 seconds.

So at any given moment, there should be about 600,000 neutrinos in you.

I'm pretty sure all those assumptions are inaccurate, but that's the number I got.

at what amounts do they start getting harmful? Also, how?

There are km wide arrays of hyper-sensible optical sensors in the artic ice to detect the odd collision now and then, so no worries.

Far far less than the charged Neutrons from ground radiation or an un-aired room (Radon). They don't matter at all in health-related things, not even in the devices relying on low-radiation steel from ancient ship wrecks.

Well, one is harmful, if it hits your DNA and gives you cancer.
