What to Look for Before Buying a Dosimeter


The number of devices and gadgets that produce radiation increases every year. Research indicates that high levels of radiation without treatment cause severe health problems. While some people who are exposed to radiation for professional reasons take the right precautions, not everyone is aware of the risks involved. Therefore, it is essential to measure radiation levels at your facility before deciding how to take proper action. One of the most widely used gadgets for measuring the radiation is a dosimeter.


There are a large number of dosimeters that are available for sale online and offline. At first, people might not be aware of radiation health problems, but they might start experiencing pain all over the body as time goes by. To prevent radiation from damaging the cells in the human body, a dosimeter can help you regulate your radiation intake.


If you are interested in a dosimeter, here are some factors to consider:





One of the most important factors that determine the kind of dosimeter you need is functionality, or scope. In some industry sectors like nuclear plants, radiation levels are high because of the scale of operation. The meters required for the nuclear industry are more sophisticated and possess all of the necessary technological features.


Similarly, radiation levels are high for some medical applications like x-rays and treating cancer patients. For industrial applications, radiation levels depend on the specific process and the amount of ionizing radiation needed. Typically, radiation levels are lower for mail-processing applications.


There are many citizens who have read about the dangers of radiation and are interested in getting a dosimeter out of curiosity or for health reasons. People who are living close to a significant source of radiation like a mobile tower often experience headaches and other pain. Monitoring the radiation levels using a dosimeter can help confirm whether the radiation source is the reason for their health problem or that it’s caused by an underlying medical condition. 



Types of Radiation


The different types of radiation include gamma, beta, x-ray, and neutron radiation. While it is possible to measure gamma and beta radiation in real-time, other methods are required to measure the exposure to neutron radiation. 


The dosimeters that measure different types of radiation differ. The kind of radiation generated depends on the industry. At medical facilities, dosimeter for measuring x-ray radiation are necessary for medical doctors administering x-ray exams.



Passive or Active


Individuals in the workplace who are vulnerable to radiation exposure are required to wear personal dosimeters that measure the amount of radiation to which they are exposed over a period of time. This ensures that the total radiation to which the worker is exposed does not exceed the legal safety limit. While gamma and beta radiation exposure are visible in real-time, the neutron radiation exposure can only be measured at the end of the year after the dosimeter is exchanged. On the other hand, the active dosimeter is handheld and has more features for measuring the radiation levels. Some companies charge extra for gamma and radiation exposure assessments, but MedPro offers free reports.

One of the main factors for choosing a dosimeter is the information you need it to provide. The active field dosimeter, which is used in high radiation areas, provides users with extensive radiation-related information. In addition to showing radiation levels at the time of measurement, the handheld dosimeter provides details like the rate of increase in radiation levels. This ensurse that people exposed to excess radiation can take corrective action. There may be a provision allowing the dosimeter to announce radiation levels. It is also possible to set the alarm levels so that the user is automatically informed when the threshold levels have been reached. Cheaper dosimeters may only have color changes to indicate the rise or fall of radiation levels. 





There are different types of dosimeters for different parts of the body. The user should wear the dosimeter in the area specified by the manufacturer of the dosimeter for accurate readings. Some dosimeters are worn on the coat or body of the user. Since the extremities of the body like the fingers, toes, and head are more likely to be exposed to radiation, there are ring dosimeters available that can be worn on the fingers or toes. The amount of radiation which is detected using these dosimeters is usually lower, usually around 0.3 MSV.





The radiation levels in different locations are likely to vary significantly. For example, radiation levels are very high at nuclear plants, so the dosimeter should be designed to have a higher range or more than 10 R/hour, which corresponds to the danger zone. For the hot zone, the radiation levels are higher (less than 10 R/hour)  while cold zone radiation levels are lower (less than 10 R/hour). Therefore, to measure the radiation levels accurately, the right meter should be used. If the range is very high, and radiation levels are low, the reading will not be accurate. On the other hand, if the radiation levels are high, and the range is on the lower end, then the meter will show the maximum range, which is less than the real radiation level.

Price and Quality


One of the factors for purchasing the dosimeter is the price, since most buyers have a limited budget. The number of features in the dosimeter, like the parameters which are measured and displayed, will be directly proportional to the price. It is also essential to check the quality of the dosimeter to find out how accurate it is. The manufacturer should also indicate the quality standards of the dosimeter, and the warranty period, especially for more expensive ones. For low-quality dosimeters to find the radiation exposure, the user will have to go to a dosimeter reader station to check the exposure. For MedPro dosimeters, the display will directly show the radiation levels, or the users can check radiation levels online. 





If you are working or living in a location with a high amount of radiation, then you will want to get a dosimeter or radiation badge. However, there are various types of dosimeters out there, so it’s imperative to know which one fits your situation. Finding the perfect device to explore the rate and dosage of radiation can be a life-saver. It can alert you if the exposure has gone above a certain threshold. 


With that in mind, you can use the information that we have provided to find your perfect dosimeter.
