Never unroll and buy a sticky tape again,you make me scared

on a side note they also tested toilet paper. the friction of the tissue and your hind quarters may tear the fabric of time a space and create a small black hole in your bathroom.

@Henri Heinonen – “How much does a X-ray detector cost?”

Any humble neon bulb (shielded from light) such as an NE2 will act as a basic GM tube and detect ionising radiation.

Looks like an easy DIY projects. I was reading more about it at http://josepino.com/discover/?scotch_tape_xrays.jpc and it doesn’t look difficult at all. How I didn’t tought about it before?

@slain34

This was an old hypothesis from some other early scientists, it was just never proven. You’ll have to ask them why they try stuff.

Why/how would they find out that it emits x-rays in a vaccuum??

Why would they be unrolling it under an x-ray light filter?

The phytoplankton causes light when disturbed.

finally! i’ve been telling people about this for years and they wouldn’t believe me that the tape on my glasses gave me x-ray vision. thx!

I thought “emit” means that the x-rays have to pass through the vacuum envelope.

In an medical X-ray tube, the cathode heats a filament causing electrons to get excited and form what is known as a negative electron cloud.

On the other end of the tube is a the anode that when flipped on is positive. Opposites attract causing the cloud to smash into the spinning tungsten initiating bremsstrahlung (breaking radiaiton)

These x-rays are then angled out of the anode and then pass through filters (keeping low kv out) and on through to the patient.

At one point in the video the experimenter holding the radiation meter says that he’s getting scared, so this setup may in fact generate quite a lot of radiations, more than I’d have guessed. There is apparently enough x-rays emitted to make a radiography of a finger.

I wonder what kind of tape do you have there in US..
I just tried with normal transparent tape and with packaging tape..
In a totally dark room I saw nothing.
Perhaps it’s the material ?

@henri heinonen good luck.

I bet there are much better materials out there then regular office tape. Can you imagine portable x-ray machines, machines that won’t need power because you could peddle them to generate x-rays. I’m really interested in scientific discoveries like this one hackaday, keep up the great posts.

How much does a vacuum pump cost? I need a vacuum of about 0.001 torrs.

How much does a X-ray detector cost?

How much does a NEUTRON detector cost?

Where can I buy deuterium or pycnodeuterium (deuterium in palladium lattices)?

Please, reply.
