Yesterday, Wednesday, the last touches on the pinhole were made, before going away on Sunday.
New led box for the pinhole. Custom made for the industrial radiographic film AGFA NDTD3.
The lid must be pierced, so that it can be in line with the pinhole’s conic lens inside the box.
Chico, chief of IRD workshop, fixing up the last bits:
Working on the drill in order to make a first outline, this will function as a model for the bigger drill later.
Choosing the proper drill in order to produce a hole with the closest possible diameter of the pinhole:

Definitive hole:
Done:

ideas…
I was just thinking about the technique of “direct contact”, meaning contact between industrial radiographic film and high-energy radioactive sources (Cs137), as described here.
In addition to the images the led pinhole projects through invisible radiation on radiographic film, the “direct contact” technique could allow me to imprint life-sized outlines and shapes of different types of contaminated matter inside the zone: objects, leaves and (why not?) the entire surfaces of much bigger volumes, such as houses, trees.
In order to imprint a house, for instance, I could get its entire outer surface, its “positive” space; and then the inside, a la Rachel Whiteread, its “negative” space.
This is definitely something to test inside the exclusion zone.
Trailer inside the zone. Belarus, November 2006.
Preview: obtaining “direct contact” images of a trailer on multiple industrial radiographic films.
…what type of images could this generate?
Well, as it happens with all experiments, I will have to try it out to see what I will get. Soon, let’s see…

11/03: contaminating leaves

New experiment: to contaminate leaves with liquid Cs137, in order to “radiograph” them with the led pin-hole camera.
Cataloguing the leaves as future radioactive sources.
Opening Cs137 glass container.
Dropping Cs137 on the leaves.
Scattering Cs137 on the leave, for the contamination to be uniform.
Contaminated leaves.
Closing Cs137 glass container.
New radioactive sources drying up.
Now, ready to be “radiographed” by the led pin-hole camera:

I thought of something to try out…
...what images will be printed on film by direct contact with a high-energy source like Cs137?

Last Friday I resumed my experiments with the pin-hole prototype I will be taking to the exclusion zone. I expect it will produce images through the very radiation which is in everything in Chernobyl.
This pin-hole can “see” gamma radiation. Radiation, unlike light, is invisible. In this case, radiation is the energy source that will imprint the film, not light, as occurs in regular photographs. The physical process, however, will be similar to that of photography with light going though a tiny hole and projecting an image.
Exemplified below is this process with light, just to clarify it:
A torch is directly facing the pin-hole...
...which projects its image backwards on the film.
What will radiation in the exclusion zone actually imprint, nobody knows. Let’s find out!
