When Steve Sillett gets up into a big Redwood, he fires an arrow, which trails a fishing line, which gets over a branch in the tree, and then you ascend up a rope which has been dragged into the tree by the line.

It's basically like a fisherman's line, a fishing line.

Where's the fish line?

Haddock?

Torpedoes ready for firing, sir.

Shoot one of those sharks, it'll keep the others occupied.

I'm after more, George, much more.

We use longlines that have one million or two million hooks.

Death rays.

Sole, snoek and tuna occur on the continental shelf along the coastline.

This equipment uses two types of rays x rays and gamma rays to detect objects such as weapons, bombs and other explosives, and drugs.

Alpha rays

Select this half line

So for direct light, it takes only one bounce, for off axis light it might take two, and for extreme off axis, it might take three.

We kill using long lines, with baited hooks every few feet that may stretch for 50 miles or more.

For most of the infrared and the ultraviolet, X rays and gamma rays, instruments need to be placed just above the atmosphere.

Haddock or boiled egg?

Chief, I'm after something big, something with real social significance.

(a) Radioactive material means any material containing nuclides which disintegrate spontaneously (a process accompanied by the emission of one or more types of ionizing radiation, such as alpha, beta, gamma or neutron radiation) and which could pose a threat to human life or health and or cause substantial damage to property or the environment.

These result in electromagnetic radiation ranging from radio waves to X rays, high energy protons and changes in the interplanetary solar winds.

X ray

Yes? We've got four torpedoes left in port tubes.

And then, when you shine sunlight at them, the sunlight will be reflected back, just as it is in the eyes of an animal.

Within this band are gamma ray pulsars and other unidentified sources of gamma rays.

But the potential advantage was that gamma rays, unlike X rays, are not influenced by breast density.
