Laser Radiation Safety Course Overview

Measures used to prevent harm from laser radiation exposure. This includes understanding laser characteristics, classification systems, and safe usage practices.

Potential harm to eyes and skin resulting from exposure to laser radiation, with varying degrees of severity depending on specific laser types.

System for categorizing laser devices according to their potential hazard levels. This guides safety procedures for handling different laser types.

Ionizing radiation has enough energy to ionize atoms, while non-ionizing radiation does not. Laser radiation is non-ionizing.

Legal requirements relating to radiation safety, which applies specifically to non-ionizing radiation, covering devices like lasers and microwaves.

The maximum radiation level allowed in a vehicle carrying radioactive materials. It's 20 Sv/hr for individuals who are not registered radiation workers.

Only registered radiation workers or individuals provided with a personal monitoring badge can occupy a vehicle carrying radioactive materials.

Individuals under 18 years of age are not allowed to occupy a vehicle carrying radioactive materials.

The shipper or licensee is responsible for the safe packaging, labeling, and transport of radioactive materials, ensuring compliance with regulations.

These regulations focus on the safe use of devices emitting non-ionizing radiation like ultraviolet lamps, microwave ovens, and ultrasound equipment.

An ultraviolet lamp designed to tan or provide cosmetic effects. Emits ultraviolet radiation between 180 nm and 400 nm.

A device using microwaves (890 MHz to 6 GHz) to heat, cook, or dry food or materials. Used in homes, restaurants, and industrial settings.

Medical or industrial devices that emit ultrasound waves (above 16 kHz). Used for diagnosis, therapy, and industrial purposes.

Radiation with enough energy to knock electrons out of atoms, creating ions. Examples include alpha, beta, gamma rays, and X-rays.

Radiation that does not have enough energy to ionize atoms. Examples include visible light, infrared radiation, and radio waves.

X-rays are produced electronically by X-ray machines when electrons jump between orbits close to the nucleus or lose energy as they pass through the electric field near the nucleus.

Alpha and beta rays are produced by radioactive decay, while X-rays are produced by electrons interacting with the nucleus in machines.

All are types of radiation, but alpha and beta are particles, while gamma and X-rays are electromagnetic waves.

Unlike radioactive sources, X-rays can be turned off immediately by simply disconnecting the high voltage.

Alpha and beta rays are both subatomic particles, but alpha rays carry positive charges and are much heavier, while beta rays carry negative charges and are lighter.

Both are electromagnetic waves, but Gamma rays originate from the decay of unstable nuclei, while X-rays are generated under controlled conditions.

A Singaporean law regulating the use of potentially hazardous non-ionizing radiation (NIR) devices, including lasers, microwaves, and ultrasound equipment.

Devices such as high-power lasers, entertainment lasers, ultrasound, microwave ovens, sunlamps, and X-ray machines are regulated under the Radiation Protection Act 1991.

The Act requires licenses for activities involving NIR devices, including manufacturing, sale, possession, use, and import/export.

These regulations, published in 1991, set detailed requirements for dealing with NIR irradiating apparatus.

These regulations, first published in 1974 and updated in 2000, focus on the safe use of ionizing radiation.

Radiation workers must be over 18 years old, registered, wear dosimeters, and receive proper training to work safely with radiation.

All radioactive materials, irradiating apparatus, and radiation areas must have clear warning labels to indicate potential hazards.

In 2007, the Radiation Protection Act was amended to transfer authority from the Health Sciences Authority to the National Environment Agency.
