Iodine-131 (I-131) is a radioactive substance produced in nuclear reactors that provides the medical isotope for nuclear medicine procedures. At high therapeutic doses, radioisotopes can be injected intravenously to effectively penetrate and destroy tumor tissue through localized radiation. Your healthcare provider will take steps to protect your thyroid from medication. Radioactive isotopes also release gamma particles, which can be captured by specialized gamma cameras during a molecular imaging process called scintigraphy. I-131 can be combined with molecular compounds to further personalize treatment and isolate radiotherapy to specific cells and their physiological functions.
I-131 radiation therapy is a treatment for hyperthyroidism and thyroid cancer. For thyroid cancer, I-131 radiation therapy is usually given after thyroid removal surgery to destroy any remaining cancerous or healthy thyroid tissue.
In I-131 radiation therapy, the radioactive substance used is radioactive iodine I-131. Patients swallow r
Radiation Detectors
A radiation detector is a device that measures nuclear, electromagnetic, or optical radiation. Nuclear radiation detectors identify nuclear radiation by measuring the emission of ionizing radiation of alpha particles, beta particles, and gamma rays. A nuclear radiation detector, also known as a Geiger counter, consists of two main components: the processing electronics and the Geiger tube. Geiger tubes are filled with low-pressure inert gases such as helium, argon, or neon. If radioactive radiation occurs, the noble gases become ionized. An anode inside a Geiger tube records the number of ionized particles that is numerically related to the intensity of radioactive radiation. The radioactivity measurements are then displayed on the LCD screen of a Geiger counter or nuclear radiation detector.
Measuring nuclear radioactivity and classifying nuclear radioactivity values is very important. For example, terrestrial gamma radiation is typically measured at 0.03 - 0.3 �µSv/h (microsieverts per hour). This "normal" range of oscillations is determined by naturally occurring radioactive elements in the ground, such as uranium and potassium. To calculate this factor, cosmic radiation must be taken into account. For example, taking cosmic radiation into account, the maximum radioactivity content at the Schneefernerhaus, Germany's highest environmental research station, is equal to approximately 110 �µSv/h. At PCE Instruments you will find three types of Geiger counters or nuclear radiation detection equipment to help you measure radioactivity: 1) alpha radiometers, 2) meters for detecting alpha, beta and gamma radioactivity, and 3) wearable Radioactive meter on the body.
Radiation Measurement Instruments
Radiation measurement instruments provide accurate radiation measurements in a variety of applications. From performing handheld gamma radiation measurements to measuring alpha and beta, radiation detectors make it easy to perform the measurements that are critical to any radiation safety program. These radiation monitoring instruments provide flexible options for most basic radiation detection scenarios.
1. What are radiation measuring instruments?
Sources of ionizing radiation have important and indispensable uses in various industries to derive maximum benefit from their applications. To ensure radiation safety for radiation professionals, patients and the public; good radiation safety practices should be followed. The most important practice is to use radiation measuring instruments to measure the radiation in and around the source.
2. What are the types of radiation measuring instruments?
The main types of radiation measuring instruments are: Surveyor, Dose Alarm Instrument, Radiation Monitoring System, Contamination Detector.
3. What are the important factors to be considered in the maintenance of radiation measuring instruments?
Instruments should be kept in the best condition.
Periodic calibration should be carried out as recommended by the authorities.
If the instrument is repaired (or) the detector is replaced, the radiation measuring instrument must be recalibrated.
4. Where can these radiation measuring instruments be calibrated?
Calibration cannot be done in any laboratory. The laboratory must be accredited by AERB (Atomic Energy Regulatory Board of India).
AERB has further made it stringent that the laboratory must be accredited by an auditing body i.e. NABL.
Such laboratories are required to calibrate the radiation measuring instruments at regular intervals.
