What is OSL Dosimetry and Radiation Detection Badges?
Radiation Dosimeter Badge x-ray badge

RadiationSafety.com utilizes OSL dosimetry in its radiation detection badges. OSL is optically stimulated luminescence; dosimetry measures ionizing radiation dosages. It allows for measuring exposure to radioactive isotopes over a specific time. Many agree that OSL dosimetry is a better alternative to thermoluminescent dosimeter (TLD) technology.

OSL dosimeter badges are the industry standard used by governments, hospitals, labs, and companies worldwide. An OSL dosimeter is a passive form of radiation detection that requires optical stimulation to function. It detects X-rays, gamma radiation, and beta particles. Some of our competitors are saying that “there’s really no difference”. Read below, and you decide. For a lower price, do you want Radiation Safety’s four-element OSL Badges, or do you want older technology that utilizes TLD badges?

Basics of OSL Technology

OSL dosimeters are materials that trap electrons from radioactive isotopes in their defective crystalline structure. Some utilize aluminum oxide (AI203) to absorb and release radioactive energy to measure the radiation dose received precisely. The OSL dosimeters store the electrons until they are released through stimulation. While heat is used to stimulate TLD dosimeters, light stimulates the elements within the OSL dosimeters. The OSL dosimeter then releases the energy stored in the dosimeter as the emitted light is measured. Since they utilize passive technology, the laboratory can read the OSL radiation detection badge multiple times without significantly fading.

Our OSL radiation detection x-ray badges are shockproof, water resistant, and unaffected by heat. These radiation monitors are durable and simple to use. With OSL technology, badges are re-readable. A second reading of the radiation dose from an OSL dosimeter may only decrease by as small as a one percent difference compared to its first reading. In contrast. TLD dosimeters cannot be read multiple times. OSL dosimeters provide a high degree of sensitivity and can give an accurate reading as low as 1 mrem for gamma-ray and X-ray particles. In addition, OSL badges measure the amount of scatter ionizing radiation. OSL radiation detection badges can also be used as area monitors. An area monitor measures the radiation in the environment over a specified period of time.

What About Late Fees and Lost Dosimeter Badges?

Our policy states that if a badge is lost, late, or unreturned, you must inform us promptly and request a replacement. Please note that a fee will be charged to your account for each lost, late, or unreturned badge. We have a 75-day grace period for lost badges or dosimeter rings, the longest in the industry. If a badge is found, a credit will be issued to your account. This credit will help offset the initial charge for the lost badge.

If you are ordering badges, we offer a wide range of frequency options When your badges or rings are returned to the lab, a report is generated. The options include monthly, bi-monthly, quarterly, and semi-annual reporting. By offering these choices, you can select the reporting frequency according to your requirements, ensuring timely monitoring of radiation exposure levels.
