What does cobalt therapy mean?
What does cobalt-therapy mean? (medicine) Radiation therapy that uses radioactive cobalt-60 as a source. (noun)
Is cobalt still used to treat cancer?
Cobalt-60 technology is currently used to treat roughly 70 per cent of the world's cancer cases treated by radiation. LHSC's last Cobalt treatment was delivered in 2004.
What are the side effects of cobalt radiation?
Because it decays by gamma radiation, external exposure to large sources of Co-60 can cause skin burns, acute radiation sickness, or death. Most Co-60 that is ingested is excreted in the feces; however, a small amount is absorbed by the liver, kidneys, and bones.
How does cobalt-60 cancer treatment work?
Cobalt-60 systems, like the Gamma Knife, deliver radiation beams through 192 circular pinholes in a fixed helmet worn by the patient. The pinhole radiation meets at the tumor site, delivering a high dose, while the surrounding healthy tissue and critical brain structures receive minimal radiation.
Is cobalt-60 still used?
Cobalt Sources Cobalt-60 is used as a radiation source in many common industrial applications, such as in leveling devices and thickness gauges. It is also used for radiation therapy in hospitals. Accidental exposures may occur as the result of loss or improper disposal of medical and industrial radiation sources.
Is cobalt therapy the same as radiation therapy?
Because these "cobalt machines" were expensive and required specialist support, they were often housed in cobalt units. Cobalt therapy was a revolutionary advance in radiotherapy in the post-World War II period but is now being replaced by other technologies such as linear accelerators....Cobalt therapySpecialtyoncology3 more rows
Is radiation worse than chemo?
The radiation beams change the DNA makeup of the tumor, causing it to shrink or die. This type of cancer treatment has fewer side effects than chemotherapy since it only targets one area of the body.
What type of cancer does cobalt-60 Treat?
Cobalt 60 (60Co) is often the ideal mode of radiation for treating laryngeal cancer.
What is cobalt treatment for breast cancer?
Radiotherapy can be delivered with a cobalt-60 unit or a linear accelerator (linac). In early stage breast cancer, radiotherapy is an integral part of breast-conserving treatment.
What are the benefits of using cobalt-60?
The advantages of Co/sup 60/ therapy over conventional x-ray therapy, stemming from the fact that in the lst instance energy absorption within the tissues is by the Compton effect and in the 2nd case by the photoelectric effect, are: (1) increased skin tolerance, (2) reduced bone absorption, (3) increase in depth dose, ...
How long does cobalt-60 stay in the body?
Beta particles are generally absorbed in the skin and do not pass through the entire body. Gamma radiation, however, can penetrate the body. The time required for a radioactive substance to lose 50 percent of its radioactivity by decay is known as the half-life. The half-life of cobalt-60 is about 5.3 years.
What is the most radioactive thing on earth?
The Most Radioactive Places on EarthUranium: 4.5 billion years.Plutonium 239: 24,300 years.Plutonium 238: 87.7 years.Cesium 137: 30.2 years.Strontium-90: 28-years.

How long does radiation therapy take after chemotherapy?
Therefore, radiation is often delayed until the end of chemotherapy in some cases, provided that the delay is not longer than 6 months. Delaying radiotherapy may result in local failure of treatment. However, there are some cases in which radiation therapy may be done first or concurrently with chemotherapy.
How is choroidal hemangioma treated?
4,25 In general, the total dosage used is about 20 Gy, given in 10 fractions for external beam radiotherapy, 25–50 Gy for plaque radiotherapy, and 16.4–20.0 Gy in four fractions for proton beam radiotherapy. Resolution of exudative retinal detachment, tumor regression, and an improvement of vision in the majority of cases treated by radiation therapy have been reported. The potential for radiation-related complications such as cataract, radiation optic neuropathy, and radiation retinopathy exists, 26 particularly for hemangioma in the juxtapapillary and macular regions. Stereotactic techniques, with improved precision, may be superior to other methods of radiation. 24 The technique of gamma knife radiosurgery has the advantage of delivering the total radiation dose in a single session. 10
What was the purpose of the Atomic Energy Commission?
At the close of World War II, the United States Federal Government created the Atomic Energy Commission (AEC) to control the peace-time uses of uranium and its fission products. Everyone saw the overwhelming and devastating results of the “Manhattan Project” by the detonation of the first atomic weapon (Code name “Trinity”) in the Jornada del Muerto desert in New Mexico on July 16, 1945. The AEC immediately began to make public scientific information which had heretofore been in the secret category. The purpose being to stimulate peace-time scientific research for the practical application of nuclear reactors for electrical power generation and for the use of fission products for industrial and medical purposes.
How often is radiation therapy given?
The therapy is usually given five times per week for 33 sessions , with the last five to six sessions in the form of a boost treatment with higher-dose radiation targeted to just the scar and the tumor bed. A treatment simulator is now considered extremely desirable, and computerised planning is essential. Cautions in radiation therapy are pre-existing autoimmune disease, because the inflammatory components of these diseases are exacerbated by radiation, and pre-existing pulmonary or cardiac disease. Collagen vascular disease and uncontrolled diabetes are also probable contraindications for radiation therapy.
Does cobalt cause goiter?
Goiter is a well-known side effect of cobalt therapy in the medical treatment of certain anemias. A reduced iodine capacity has been seen in patients given 20-30 mg Co per day ( Kriss et al., 1955; Roche and Layrisse, 1956; Schirrmacher, 1967 ). Usually these adverse effects are regarded as reversible and probably reflect the inhibition of tyrosine iodinase by cobalt (II) ions. Thyroid changes were also noted among the Quebec beer drinkers ( Roy et al., 1968 ). Upon autopsy, 11 out of 14 glands examined showed significant changes, with reduced follicle size. Out of 12 patients treated for anemia with cobalt by Duckham and Lee (1976), one developed hypothyroidism, but it was uncertain to what extent this side effect could be related to the cobalt treatment.

Is cobalt a hypothyroid?
In a cobalt production plant, a subclinical hypothyroid status has been reported in workers with a mean urinary cobalt concentration of about 70 μg/g creatinine ( Swennen et al., 1993 ); in contrast, in Danish plate painters exposed to cobalt-zinc silicate (mean cobalt urinary concentration, 10 μg/g creatinine) increased concentrations of total and free serum thyroxine have been found ( Prescott et al., 1992 ). A follow-up study in the cobalt production plant ( Lantin et al., 2011) recorded a significant reduction in exposure (median urinary cobalt concentration, 4 μg/g creatinine) and no effect on thyroid parameters.
What is a C obalt 60?
C obalt-60 units supply gamma radiation of two monochromatic wavelengths (1.17 and 1.33 mev), and the soft beta radiation is easily filtered out by approximately 0.16 mm of steel. Such units therefore have made possible the world-wide use of the equivalent of supervoltage roentgentherapy. Patients with some types of cancer formerly unfavorable for radiation treatment now have a better outlook. Palliation of distressing symptoms or prolongation of life by remissions, as in the lymphomas, are easier to achieve with much less discomfort to the patient. Because of the skin-sparing nature of supervoltage radiation, preoperative irradiation can be followed by the classical surgical procedures in cases in which poor results would be expected from either type of therapy alone, and the combined effects are now being investigated in cancer of the lung, urinary bladder, and breast.
Is radiation treatment better for cancer patients?
Patients with some types of cancer formerly unfavorable for radiation treatment now have a better outlook. Palliation of distressing symptoms or prolongation of life by remissions, as in the lymphomas, are easier to achieve with much less discomfort to the patient.

Cobalt might cause heart problems, lung disease, hearing loss, and vision loss in people who are exposed to cobalt dust in certain industries. Special Precautions and Warnings.
Is Cobalt 60 a good tomotherapy?
In this paper, we demonstrate that Cobalt-60–based tomotherapy approach is capable of both highly conformal intensity-modulated dose deliveries and viable image guidance. While it may seem that the addition of more complex beam collimation and megavoltage imaging to cobalt may complicate a simple technology, and perhaps make the device too complicated or expensive for worldwide distribution, we believe that it is important to establish full modern radiation therapy with a cobalt unit. It is quite clear that in the coming decade, the standard of care for radiation therapy will require image guidance and that radiation units incapable of imaging at the time of delivery will no longer be used in clinics. The development of tomotherapy type approaches with Co-60 also indicates that the potential for use of more sophisticated machines as proposed by Kron et al.incorporating MRI[17] may also translate into actual practice. We believe that there are considerable clinical and economic advantages in further investigating modern delivery with Co-60.
Is Co-60 a rotational implementation?
This report will review the results of experimental investigations of the potential of Co-60–based IGRT via tomotherapy — a rotational implement-ation of IMRT.[8,5] Measured conformal dose distributions achieved with an in-house Co-60 tomotherapy benchtop apparatus will be compared to the corresponding treatment plans. The results of investigations of Co-60 megavoltage computed tomography (MVCT) for image guidance[5,6] will also be shown. The findings of this work support the fact that there is ample potential for administering modern radiation therapy with a cobalt unit and encourage further investigations and development.
Is Co-60 a conformal irradiation?
The findings to date confirm the viability of Co-60–based tomotherapy for conformal dose delivery. Figure 2shows two examples of conformal irradiations planned for the delivery with the in-house cylindrical treatment phantom — a ring pattern [Figure 2a] and a standard conformal avoidance ‘C’ plan [Figure 2b]. These plans were implemented to determine whether the inverse treatment planning system would be able to generate an optimized and accurate dose distribution for simple but challenging geometry, including the ability to protect the central critical structure from unwanted radiation.
