I was wondering how those who were on the Moon back in sixties could record that event on camera, which was probably based on feromagnetic writing, or such thing? help, discuss.

The Apollo astronauts carried specially-equipped Hasselblad medium-format film cameras. I don't know if the film was stored in a lead pouch or not, but in any case the radiation levels they encountered on the Moon were not too high (luckily there were no major solar flares during Apollo missions). The primative computers on board did use ferrite cores, which are especially resistant to radiation damage compared to modern semiconductor memory. Of course these computers did not have enough memory to process anything like a digital image, and there were no CCDs.
The technology of the 1950's and 1960's was, if anything, less sensitive to radiation than the technology of today---the elements were big and klunky, and there was little a single cosmic ray hit could do to it. Vacuum tubes were used for many defence-related electronics because they are impervious to EMP.

The answer is yes and no. Cosmic radiation can erase a bit or two on a tape or in some sort of computer memory, but it is not intense enough to erase the whole thing.

I believe only magnetic fields can erase data, don't confuse that with electromagnetic radiation.
The Earth's magnetic field is very weak, so that's why credit cards, tapes, and such things work here.

No, it isn't that strong. In fact, it may surprise you to know that you are exposed to nearly as much cosmic radiation in an airline flight at 30,000 feet as the astronauts on the Moon were!

It is more likely the strip came in contact with, in my case, a pace maker. The store security gates and scanner for anti-theft will all erase or distort rendering it useless

Cosmic radiation, will create noise in the images . It will not erase it, it is not energetic enough to do that.
