Radiation Protection Service Radiation Protection Service University of Glasgow University of Glasgow Lecture 1:Radioactivity Basics Radioactive decay processes. 4. Gamma decay: Nucleons have quantised energy levels - emitted γ-ray photons from a particular nucleus have a unique γ-ray spectrum. ...
Knowledge Check X-rays, gamma rays and microwaves travelling in vacuum have Asame wavelength but different velocities Bsame frequency but different velocities Csame velocity but different wavelentghs Dsame velocity and same frequencySubmit What physical quantity is the same for X- rays of wavelength...
However, studies on clustered DNA lesions have been using acute and high dose rates of ionising radiation. D. P. Hayes suggests that at a low dose/dose rate (as applied in this study) repair mechanisms might not be activated resulting in elimination of the cell by apop- totic or mitotic...
Keywords: gamma radiation; herbs; phenolic compounds; aflatoxin B1; ochratoxin A; chromatography 1. Introduction There is currently a high demand for medicinal and aromatic plants, due to their combined aromatic and bioactive properties [1,2]. One of the most significant compounds which confer ...
In addition to studies described here, there are other non-cancer effects of ionising radiation, particularly cardiovascular disease, that have been well studied using acute radiation exposure. However, specific experiments to establish the effect, if any, of dose rate have yet to be addressed. ...
DNA radiation damage and asymmetric somatic hybridization : Is UV a potential substitute or supplement to ionising radiation in fusion experi- ments? Physiol Plant 85 : 319-324 .Hall RD, Krens FA, Rouwendal GJA (1992a) DNA radiation damage and asymmetric somatic hybridization: is UV a ...
As an engineer who is also VERY familiar with the ocean and it’s lifeforms, ignoring this amazing coincidence is incredibly irresponsible. They are spending $180 Million a year to verify Iran compliance on nuclear weapons, but “they” can’t up with $600 for a Gamma Scint Radiation scan...
Radiation which is called "ionizing" can be absorbed by tissue and break molecules apart, such as gamma rays and x-rays, are known to cause cancer. The concern is that the cell phone and it's antenna (the source of the radiation) are held close against the head)...
At the point where the pulse was emitted “the electromagnetic field strengths would be capable of totally vaporising and ionising all known materials, shredding them into hot plasma”, says Wayne Cannon of York University in Toronto, Canada, though the pulse was harmless by the time it reached...
Work alongside local service leads to ensure organisations deliver statutory obligations with respect to the safe use of ionising radiation. Support and line manage clinical scientists, contribute to staff development and assist in the supervision of trainees undertaking the STP programme or equivalent. ...
