Dangers of Radioactivity

Radioactivity refers to the particles which are emitted from nuclei as a result of nuclear instability.
Exposure to radioactivity comes from a small number of natural and human activities.
Protracted exposure, or exposure over a long period of time, can increase the chances of developing certain types of illnesses, such as cancer.
High doses can cause noticeable ill health effects up to and including death within days or months of exposure.
Low doses spread out over long periods of time don’t cause an immediate problem to human health but can have long term effects.

Radiation sickness is a condition that occurs when the body absorbs a high dose of radiation, often over a short period of time.
Symptoms of radiation sickness include nausea, weakness, hair loss, skin burns or diminished organ function.
The most common cause of radiation sickness is a nuclear reactor accident, such as the Chernobyl and Fukushima incidents.

Radioactive contamination, unlike exposure to ionizing radiation, involves radioactive substances remaining on materials or living tissue.
If individuals ingest (swallow), inhale or absorb radioactive substances, they can cause radiation damage internally.
The level of harm will depend on the nature of the radiation involved, its chemical form and the amount.

Using lead containment and other methods, radioactive materials should be safely stored to prevent contamination or radiation exposure.
It’s also critical to have access to equipment that can detect radiation, so as to identify areas of concern.
People who work with radioactive materials are advised to use protective clothing and equipment, limit their exposure time, and regularly monitor their level of exposure.
In areas where exposure is likely, such as hospitals or laboratories, rigid safety protocols are needed to prevent both acute and long-term effects of radiation exposure.
