Radiation is made up from three types of particle or ray depending upon your quantum interpretation! They are commonly referred to as –
- Alpha rays. Which essentially a stream of helium atoms.
- Beta rays. An electron stream.
- Gamma rays. These consist of high energy photons either emitted during nuclear reactions, or spontaneously from the decay of the nucleus of radioactive atoms.
Some types of radiation occur ‘naturally’ and form part of the cosmic background resulting from cosmic radiation from stars, and the emissions from our sun, but realistically they are also the result of nuclear processes. The commonly known X-ray is a form of radiation with a wavelength between that of gamma rays and ultra violet light.

Osteoporosis is a disease in which the bones become porous and brittle. The bones can break easily and tend to heal slowly. The disease seems to affect women who have passed through their menopause, although it has been known to occur in younger people.
The effects of osteoporosis can lead to severe pain, weakening of joints and curvature of the spine. Some of these effects are listed.
- Effect on Bones and Body Joints. Osteoporosis causes thinning of the bone mass, the spongy inside of the bone is progressively eaten away. This tends to affect the mobility and general activities of the sufferer. The bones have become so embrittled that even a slight bump into a hard object can cause a bone to fracture. The common locations for such fractures are the wrist, hip, and knee.

The majority of volcanoes exist throughout the Pacific ‘ring of fire’ although volcanoes do occur at any location where tectonic plates are either converging or diverging. The volcano is essentially a break in the earth’s crust at these points.
The effects of a volcanic eruption can differ. They can be simple eruptions of steam outflow and minor gas discharge, or they can be massive explosions which release tremendous amounts of gases, lava, rocks, and volcanic ash. Such large eruptions can cause considerable amounts of damage, affect the health of people and lead to them being evacuated if an eruption is deemed to be imminent.
Effects of a Volcanic Eruption.
