Beta particle - Wikipedia, the free encyclopedia
Beta particles are high-energy, high-speed electrons or positrons emitted by certain types of radioactive nuclei such as potassium-40. The beta particles emitted are a form of ionizing radiation also...

Ionizing radiation - Wikipedia, the free encyclopedia
Ionizing radiation consists of subatomic particles or electromagnetic waves that are energetic enough to detach electrons from atoms or molecules, ionizing them. The occurrence of ionization depends ...

Animated lesson with interactive activities, simulations and adaptive test introducing penetration, uses and dangers of alpha, beta and gamma radiation. ... For the moment we'll say that alpha and beta radiation consist of tiny particles, much smaller than an ... The doctor then uses a special camera called a ‘gamma camera',

Beta emitters have many uses, especially in medical diagnosis, imaging, and treatment: ... Beta radiation can cause both acute and chronic health effects. Acute exposures are uncommon. Contact with a strong beta source from an abandoned industrial instrument is the type of circumstance in which acute exposure could occur.

Radioactive substances give out radiation all of the time. There are three types of nuclear radiation: alpha, beta and gamma. Alpha is the least penetrating, while gamma is the most penetrating. Radiation can be harmful, but it can also be useful. ... Uses of beta radiation...

Two varieties of radiation have been used so far – gamma radiation and beta radiation. The first FDA-approved device uses beta radiation, but a gamma radiation device is expected to be approved within a few months.

Aims Intracoronary radiation therapy (ICR) has significantly improved the long-term outcome after treatment of diffuse in-stent restenosis (ISR). The efficacy of drug eluting stents in this setting remains less well defined.

Intracoronary -radiation therapy; The Beta-Cath device (non-centred ß-emitter, Novoste Europe SA/NV Brussels, Belgium) was used in all patients. This device consists of a hand-held, multiple-use transfer device, a 5F delivery catheter, and a 40- or 60-mm source train of strontium-90 seeds, depending on lesion length.

The device consists of three components: 1) the transfer device, which stores the radiation source train and allows its positioning within the catheter; 2) the delivery catheter, which is a 5 Fr multilumen noncentered catheter that uses saline to send and return the radiation source train;
