Best Radiation Detector for Home Use

A dosimeter is known to be a kind of instrument or device that is used in relation to radiation.

When there is external ionizing radiation (such as Gamma rays, X-rays, high energy Beta rays, and high energy Ultraviolet rays), there is a need to measure the dosage or range of the radiation that is being exposed into the atmosphere.

This is where the Dosimeter device comes into play, this instrument helps to measure the accurate dose or exposure to the external ionizing radiation over an extended period of time.

There are a lot of different brands which make dosimeter devices but they all have one goal in common; To ensure that the device itself is able and capable enough to carry out its function of recording the radiation dosage over a period of time.

Buying Guide for the Best Dosimeters

Getting to know the best kinds of dosimeters can be quite tasking but there are some hacks that you can put in place in order to choose a good brand with the best dosimeter for measuring radiation.

You will need to take certain things into consideration such as the different kinds of dosimeters that are out in the world today, the different brands that make these dosimeters, the pros of the dosimeters, the cons of the dosimeters and the reviews given by people who have used that particular brand or kind of dosimeter.

The following features need to be considered when you are planning to buy personal or radiological dosimeters so that you can get the best dosimeter that will be perfect for you:

  1. Usability Before getting a dosimeter, you will need to note if the kind you would like to get is suitable to meet your needs. There is no point in getting an over hyped radiation dosimeter model if it is not best suited for your uses.
  • Pros: It is not unusual for a radiological dosimeter to have pros, in fact, it is seen as a good thing. Before deciding on getting the dosimeter, you will need to weigh the pros against the cons to see if the pros outweigh the cons.
  • Cons: When an item has some pros, it is bound to have a number of cons as well; it is a natural law. Having cons despite pros does not automatically mean that the item or product (in this case, dosimeter) is bad. But you will need to note the number or intensity of the cons, if you are unable to accommodate the amount of cons found in that particular dosimeter, then there is no need for you to get it.

How Do I Use A Dosimeter?

A dosimeter is used for very sensitive measurements when it comes to radiation and radiological activities.

We know now what a dosimeter is, and what it is used for, so this then begs the question ‘How can I use a dosimeter?’.

There are different kinds of radiation dosimeters such as the body dosimeter badge and the ring dosimeter badge.

For the Body Dosimeter Badge

  • Wear your body dosimeter badge on the parts of your body that are prone to radiation exposure (between your neck and waist).

For the Ring Dosimeter Badge

  • Wear your ring dosimeter badge on the finger that is most prone to exposure, ensure that the label faces outward from your hand.
  • With gloves – wear your ring badge before putting on the gloves, this is done to ensure that the ring badge stays away from being contaminated. When removing your gloves, try to make sure that you do not leave or forget the ring badge inside of the gloves.

Ensure that you do not share your dosimeter badge with anyone, if it gets missing do well to notify your company or organization so that you can get a replacement as soon as possible.

In addition, do your best to exchange your old dosimeter badges and get new badges quarterly, this is done to ensure that you get the best dosimeter and still at good quality so you can stay protected.

Best Dosimeter FAQ

How does a dosimeter work?

  • Dosimeters work by measuring radiation levels and originally they were film-based, meaning that the film gets imprinted on when the dosimeter badge is exposed to radiation.
  • A Thermoluminescent Dosimeter (TLD) contains a crystal which is made of lithium fluoride and is very radio sensitive so when the atoms in the crystal are exposed to radiation, the electrons reach an excited state where the crystal gets heated (at a high temperature). Here, there is a release of energy in the form of visible light and this is what is then used to measure the dosage of the radiation (Thermoluminescence).

How much radiation is too much?

  • The maximum dose limit set by the Nuclear Regulatory Commission for the whole body especially in primary occupational practices relating to radiation is 5,000 millirems per year.
  • The maximum dose limit set by the Nuclear Regulatory Commission for the skin and other extremities such as the hands and fingers is 50,000 millirems per year.

Any value gotten or recorded that is higher than the value ranges here is too much, too toxic and too dangerous as it will have ill effects on the human body.

Where is a dosimeter found?

  • A dosimeter is found in companies where there are radiation workers that deal with certain sealed and unsealed radioisotopes, operate X-ray machines, this instrument helps them to ensure that they carry out their activities at a safe radiation level.

What type of radiation does a dosimeter measure?

  • A dosimeter is capable of measuring external ionizing radiation such as Gamma rays, X-rays, high energy Beta rays and high energy Ultraviolet rays but a dosimeter is unable to measure or detect beta rays from certain isotopes that are of low energy such as Tritium, Sulfur-35 and Carbon-14.

What is the difference between a sound level meter and a noise dosimeter?

  • Though both instruments measure noise levels, the sound level meter is seen to be bigger in size and it can be used in an environment or in the workplace while a noise dosimeter is used in places where a sound level meter is not safe or practical to use (confined spaces or places with a high fire risk).

Final Verdict

Dosimeters are very important in ensuring and securing the safety of workers in the radiation industry, they help to make sure that the radiation levels surrounding the work done in a radiological company is at safe levels for the employees.

This fact alone goes to show the importance and necessity for every radiological company to provide dosimeters for their workers.

A good dosimeter will go a long way in saving a person’s life so it is key that you carefully cover all your bases and get all the information you need when deciding to get a dosimeter for your work or daily use.
