What are the radiation hazards

Radiation is everywhere in our daily lives. It comes from nature and human activities. When it comes to radiation, many people may feel worried about its impact on health. In fact, radiation is not always dangerous. Its harm mainly depends on the type and dose of radiation.

Radiation is divided into ionizing radiation and non-ionizing radiation. Ionizing radiation includes X-rays, gamma rays and certain high-energy particles, which have enough energy to damage DNA in cells and may cause cell damage or cancer. For example, long-term exposure to high doses of ionizing radiation may increase the risk of cancer. X-ray examinations and radiotherapy in medical treatment are all applications of ionizing radiation. Although they have potential risks, the risks are controllable under the guidance of a doctor.

Non-ionizing radiation includes ultraviolet rays, microwaves, radio waves, etc. These radiations have low energy and generally do not directly damage DNA. Common sources of non-ionizing radiation include sunlight, mobile phones, Wi-Fi, etc. Excessive exposure to ultraviolet rays may cause skin aging, sunburn, and even skin cancer. It is very necessary to take protective measures such as applying sunscreen and wearing a hat when going out. As for radiation from mobile phones and Wi-Fi, current research has not confirmed that they have significant health hazards to the human body.

In daily life, using electrical appliances properly and paying attention to the radiation level of the living environment are effective measures to reduce radiation hazards. For example, try to reduce unnecessary X-ray examinations, keep a certain distance when using mobile phones, and avoid long-term contact with high radiation sources. Although radiation is everywhere, as long as we treat it scientifically and reasonably, we can completely minimize its impact on health.

The hazards of radiation depend on its type and intensity. Understanding the basics of radiation and taking appropriate protective measures can help us better protect the health of ourselves and our families. I hope this article can provide you with some practical information and advice.
