Is There A Cure For Radiation Exposure?
Exposure to high doses of ionizing radiation within a short time can cause radiation poisoning. There are both long-term and short-term effects of radiation poisoning, including death.
However, not all forms of radiation exposure cause radiation sickness. Also, radiation sickness is not necessarily fatal. The Chernobyl nuclear disaster of 1986 provides a relevant point of reference.
A total of 28 firefighters and workers died from radiation poisoning at Chernobyl. About 100 others were diagnosed with radiation sickness. They all survived, however.
Introduction To Radiation Detectors
We hear of radiation therapy, especially for certain types of cancer. We also hear of radiation disasters such as the Fukushima Daiichi nuclear power plant accident in 2011.
Radiation, thus, can be both helpful and harmful to humans. Hence the need to deepen our understanding of what radiation is all about. That is also why we need radiation detectors.
Treatment For Radiation Poisoning
Radiation poisoning happens due to exposure to a high dose of ionizing radiation, usually over a short time. Such exposure allows radiation to get inside the human body through breathing, and/or open wounds.
The consequent damage caused to our internal organs is what we refer to as radiation poisoning. Other names for radiation poisoning are radiation sickness, or acute radiation syndrome (ARS).
What’s the Difference Between a Geiger Counter and a Personal Radiation Detector?
It is common in popular culture to refer to all types of radiation detection instruments as Geiger counters. That, however, is a mistake.
There are different types of radiation detection instruments. Not all of them are Geiger counters. A personal radiation detector (PRD), for example, is different from a Geiger counter.
What Instrument Is Routinely Used To Check A Person’s Exposure To Radiation?
Any kind of radiation exposure is harmful to humans, irrespective of the dose being low or high. There are differences in the biological effects of low- and high-dose radiation, of course. But, there are adverse health impacts of low-dose ionizing radiation as well as beneficial ones.
What’s The Difference Between Alpha, Beta, and Gamma Radiation?
Radioactivity is the process of unstable nuclei spontaneously decomposing to attain a more stable nuclear status. The decaying process continues until the unstable nuclei gain stability. Alpha, beta, and gamma, as named by Rutherford, are three such processes.
How Can Radiation Be Controlled And Safely Used In Medicine
The World Nuclear Organization informs that the use of radiopharmaceuticals for diagnosis has a growth rate of more than 10%annually. In addition, 7.5 million cancer patients globally were receiving radiation-based treatment by 2013.
The flip side is that ionizing radiation in health care is the single largest artificial source of radiation exposure for patients, healthcare workers, and the population in general, according to WHO (World Health Organization).
How Is Radiation Used In Medicine
Radiation is an energy that can be of two types: ionizing and non-ionizing. Radiation in the electromagnetic spectrum with energy efficiency too low to cause ionization is known as non-ionizing radiation. Infrared (IR), microwave (MW), radio frequency (RF), ultraviolet (UV), etc. are typical examples.

Radiation Measurement: 5 Tips to Choose the Right Device for the Job
One look-back at the Chornobyl disaster will make you understand how the danger of radiation looms large on the earth right now. The scariest aspect is that radiation has no color or odor, and is hence undetectable. Imagine walking straight into a highly radioactive zone without sensing the impending doom. The personnel working in radioactive facilities or those responsible as first-responders in potential radiation risk situations need solid protection to stay safe from the perils of exposure.
The original detection principle was discovered in 1908, but it was not until the development of Geiger counter in 1928 by Hans Geiger and Walther Muller (about 100 years ago!) that the Geiger-Müller counter became a practical instrument. Since then it has been very popular due to its robust sensing element and relatively low cost to determine whether an object was radioactive and emitting radiation. It is also potentially capable to detect the amount of particle emission by the radioactive substance.
What Type of Crystal Is Used In Radiation Detection Meters?
Radioactive isotopes leave a unique signature in the form of particles they emit and they are measured by radiation detection meters. These detectors play a key role in areas like nuclear power generation, border security, nuclear medicine, proliferation, decommissioning and decontamination.
Due to the complexity of the detection process and the scarcity of Helium-3 – the preferred choice for neutron detection in various applications – sensitive materials are necessary. And organic and inorganic scintillating crystals are good alternatives.
Crystals scintillate when exposed to X-rays and the most common distinction is between inorganic and organic crystals.
Ways of radiation penetration into human body
The main sources of radiation are not the potentially dangerous nuclear objects in cases of emergency but rather the natural sources. A person receives the main dose of radiation from natural radiation sources like outer space.
Why Measure Radiation?
Radiation including Alpha and Beta particles, and Gamma and X-rays, are useful to us in various fields like medicine, agriculture, research, power, military, and many other possible fields. But uncontrolled exposure to radiation can be harmful, even fatal. Measurement of radiation is, therefore, essential when dealing with it. Detection and measurement of any background radiation are also necessary because that too can exceed safety levels. Finally, detection and measurement are necessary to prevent illegal transfer of radioactive material across national borders.
Understanding Personal Radiation Detectors
For anybody working in a field with risks of exposure to radiation, it’s supremely important to understand the basics of choosing appropriate devices for measurements. Getting an idea of the intensity of radiations is the first step of planning on safe operations.
Fire Responders’ Guide to Dealing With Radiation
It’s unfortunate but true – weapons of mass destruction are in the wrong hands. Today, the probability of a fire respondent being called upon to tackle situations where fires are caused by anti-state elements using advanced weaponry, are much common than what you’d realize. For any job that puts you in a situation of life risk to you, your colleagues, and several others, there’s no such thing as over preparing.
Personnel monitoring is one of the most crucial aspects of worker safety. Without the use of radiation exposure monitoring devices to constantly monitor and record an individual’s exposure levels, it would be impossible to see whether the worker is going over their radiation limits. The level of radiation the worker accumulates depends greatly on the radiation dose they receive and the time they spend in hazardous areas. So when a person is exposed to high power sources of radiation or spends a longer amount of time in such a place, they will receive a larger dose.
Obtaining Radiation Intelligence
Research into radiation reconnaissance first started in the 1980s amidst speculation of a possible nuclear war. Devices meant to measure radiation were first made in Hungary for use in the battlefield. However, the failings of technological expertise meant that these devices were not very effective. It was after the Chernobyl disaster in 1986 that more serious research was conducted in this field, so as to perform a thorough analysis of the results of the disaster. Since these times, we have seen quite a few advancements made in the field.
