Application of gamma rays in medicine

Gamma rays are widely used in medicine and specifically in the area of oncology to treat malignant and cancerous tumors during a process called gamma knife surgery. In this type of treatment, concentrated beams of gamma rays are directed at tumors in order to kill cancerous cells The main applications of Gamma rays in the field of medicine are- Radiation therapy- These therapies are used to treat infectious and cancerous tumors. In this process, high energy gamma rays are directed by implanting or injecting a radioactive isotope near the tumor to kill it Therapeutic use of Gamma Rays [edit | edit source] Gamma rays are usually used therapeutically in the branch of medicine called Oncology. They are utilized to treat cancerous and malignant tumors in the human body Gamma-ray imaging in medicine Introduce a gamma-emitting radioisotope into body (attached to a biologically interesting molecule) and observe how it distributes through different organs. Diagnostic nuclear medicine Functional imaging - shows how organs are working, not just their structure (physiology not just anatomy

Unlike alpha and beta particles, which have both energy and mass, gamma rays are just pure energy. 11 The penetrative power of gamma rays is such that several inches of a material such as lead, or several feet of concrete are required as a barrier to stop them. Gamma rays can pass through the whole human body easily, potentially causing severe damage to tissue and DNA Application of Gamma Rays Gamma rays are ionizing radiation which can kill living cells. They are used to treat malignant tumours in radiotherapy. Gamma rays can also act as surgical knifes in surgery

The cameras are mounted on a rotating gantry that allows the detectors to be moved in a tight circle around a patient who is lying motionless on a pallet. What is Positron Emission Tomography (PET) Use of Gamma Radiation Techniques in Peaceful Applications. Edited by Basim Almayahi. University Of Kufa. This book deals with gamma radiation in many fields, which encompasses diverse factors that affect human and animal life inside an environment. These fields include nuclear and medical physics, industrial processes, environmental sciences. Major uses of imaging based on gamma rays include nuclear medicine and astronomical observations. In nuclear medicine, the approach is to inject a patient with a radioactive isotope that emits gamma rays as it decays. Images are produced from the emissions collected by gamma ray detectors. References at the end are listed. 9 10 S. Martin, E. Duncan, in Implantable Sensor Systems for Medical Applications, 2013 8.3.4 Sterilisation by exposure to radiation. Methods of sterilising medical devices using radiation include X-rays, gamma rays, and electron-beam (ISO 11137-1, 2006).Their suitability for the sterilisation of implantable sensor systems depends on compatibility with the sensor materials and on the volume of product

X-Rays-Medical Applications  X-rays are used in medicine for medical analysis.  Dentists use them to find complications, cavities and impacted teeth.  Soft body tissue are transparent to the waves.  Bones and teeth block the rays and show up as white on the black backgroun However, gamma rays can also be used to treat cancer. Radiation therapy, or radiotherapy, uses high-energy gamma rays to kill cancer cells and shrink tumours. Gamma Knife Radiosurgery is a special form of radiotherapy. It uses beams of gamma rays to treat injured brain tissue by damaging the DNA of dangerous cells Even though these rays are dangerous with high exposure, they are still used in the medical field for cancer treatment and for imaging equipment such as x-rays. Your exposure amount can only be measured using a Geiger counter and to determine what can stop gamma radiation. This is the reason why during the x-ray process, you will use a lead apron Shielding characteristics of nanocomposites for protection against X- and gamma rays in medical applications: effect of particle size, photon energy and nano-particle concentration Radiat Environ Biophys

Another common use of gamma rays is in the treatment of certain types of cancer. Gamma rays are a form of electromagnetic radiation, and they have the greatest energy of all forms of.
  4. Gamma radiation can kill living organisms, including bacteria. Therefore, gamma radiation is used for the sterilization of medical devices. X-Rays soft X-rays are used to take still images, known as radiographs. X-rays may penetrate the human body but are absorbed by the more bone-like parts of the bone
  5. istered to a patient, a gamma camera can be used to form an image of the radioisotope's distribution by detecting the gamma radiation emitted.
  6. Likewise, in a PET scan, which stands for Positron Emission Tomography, the premise is the same, except it is beta radiation that is used as a radioactive tracer rather than gamma radiation. Whilst beta radiation is not a strong as gamma radiation, it is still able to penetrate skin tissue unlike alpha radiation, and thus can be used in medical imaging

Applications of Ultraviolet. The intensity of UV radiation reaching the skin is highest with a high-power lamp positioned close to the patient with the radiation beam perpendicular to the skin's surface. Penetration is deepest for UV radiation with the highest intensity, longest wavelength, and lowest frequency In theory, switching products from gamma to X-ray is very easy and would reduce the industry's dependence on Co-60 sources. But practic ally, many barriers force manufacturers to keep using Co-60 sources. The main reasons are the high cost required to revalidate products from gamma to X-ray, the non-availability of X-ra Apparatus with a scintillating crystal, photomultiplier, and data acquisition components.
