Over-radiation

Androgen ablation with a luteinizing hormone-releasing hormone (LHRH) agonist plus an antiandrogen should be used prior to radiation therapy for patients with locally advanced prostate cancer to improve outcomes over radiation therapy alone. 

Failure pattern analysis of the C ALGB and French trials showed that local persistence or failure still occurred in around 80% of patients despite the ChT however, the incidence of distant metastases as a first site of failure was significantly lower in the combined modality group, confirming the theoretical potential that ChT could effect distant micrometastases. Subsequent meta-analyses confirmed the superiority of induction ChT, using a cisplatin-based regimen, and RT over radiation alone (60,65). Thus, sufficient evidence was now in place to establish induction chemoradiation as a world-wide standard of care. To further improve outcome, steps would have to be taken to improve local disease control as well. 

As a top-priority urgent measure supporting initiation of preparative works on VVER SNF management, one needs creating appropriate conditions for safe carrying out and control over radiation-hazardous works and normal hygiene and sanitary conditions for persoimel (fimctioning of decontamination room, radiation safety service... 

Here e1 is the fundamental transverse microscopic electric held operator and b is the corresponding magnetic held operator. The superscript on the electric held operator designate its transverse character with respect to the direction of propagation, redundant in the case of the magnetic held as it is intrinsically transverse, namely, divergence-free, since it arises from the curl of a vector potential held a(r). Since the electric held also derives from a(r), we concentrate first on the second-quantized form of this vector potential, which is cast in terms of a summation over radiation modes as follows ... 

Q5. How does convection by poc and air have an advantage over radiation from refractory or an electric element ... 

Tests indicate that shielding effectiveness of component shields at radio frequencies above 10 MHz may vary from 10 to 25 dB over radiation from no shields. 

Transport index (TI) assigned to a package, overpack or freight container, or to unpackaged LSA-I or SCO-I, shall mean a number which is used to provide control over radiation exposure. 

Eisenhower s announcement failed to quiet the debate over radiation problems because new recommendations of the National Committee on Radiation Protection soon produced another controversy. The issue stemmed from a decision of the International Commission on Radiological Protection, made public in early 1959, to advise a maximum permissible level for whole-population exposure firom internal emitters of one-hundredth of the occupational limit for gonad-seeking radioisotopes and one-thirtieth of the occupational limit for radioisotopes that do not affect the reproductive cells. Most internal emitters, including strontium 90, cause somatic rather than genetic damage. The action of the ICRP... 

The uproar over sea disposed of low-level wastes was largely a result of growing public concern over radiation hazards. As one journalist observed, commenting on the protests over the Industrial Waste and Walker Trucking license applications "Since American sensitivity to the... 

The last five chapters have shown how the radiation fields of an optical waveguide can be represented in different ways. In Chapter 24, we introduced the notion of leaky modes to describe the bulk of the radiation field close to the waveguide axis at distances sufficiently far from the source of exdtatioa The remaining portion of the radiation field corresponds to a space wave, as defined in Eq. (24-1). The same radiation field can also be represented either by an expansion over radiation modes, as we showed in Chapter 25, or by a superposition of the fields of point dipole sources, using the Green s function techniques for waveguides described in Chapters 21 and 34. In this chapter, we show how to find the space-wave component of the radiation field by formally decomposing either representation into leaky modes and a space wave.
