Introduction Radiation-induced bystander effect (RIBE) is a phenomenon in which radiation signals are transmitted from irradiated cells to non-irradiated ones, inducing radiation effects in these cells. RIBE plays an effective role in radiation response at environmentally relevant low doses and in radiotherapy, given its impact on adjacent normal tissues or those far from the irradiated tumor. ...

Bystander or non-targeted effect is known to be an interesting phenomenon in radiobiology. The genetic consequences of bystander effect on non-irradiated cells have shown that this phenomenon can be considered as one of the most important factors involved in secondary cancer after exposure to ionizing radiation. Every year, millions of people around the world undergo radiotherapy in order to cu...

background: the health effect of rapidly increasing everyday exposure of humans to radiofrequency radiation is a major global concern. mobile phone jammers prevent the mobile phones from receiving signals from base stations by interfering with authorized mobile carriers’ services. in spite of the fact that mobile jammer use is illegal, they are occasionally used in offices, shrines, conference ...

Background: The biological effects of radiation on radiology personnel are divided into two groups of deterministic effects and stochastic effects. Due to the effects of radiation on health, radiology staff may be afraid of radiation. Younger personnel with little work experience, compared with older personnel, have higher level of fear. The fear among radiology personnel, like employees of var...

Introduction: Today ionizing radiation (IR) plays an important role in medicine, both in diagnostic and therapeutic field. Doctors, medical staff and patients are all in danger of side effects of IR so there is a need to protect them against deleterious effects of ionizing radiation.  Thymus vulgaris has biological activities like antioxidant and antibacterial activity. Aim of...

Radiation damage is to a large extent caused by overproduction of reactive oxygen species (ROS). Radioprotectors are agents or substances that reduce the effects of radiation in healthy normal tissues while maintaining the sensitivity to radiation damage in tumor cells.Radioprotectors are agents or substances that reduce the effects of radiation in healthy normal tissues while maintaining the s...
